Risk and Due Diligence Foundations: What to Verify Before You Commit

The Verification Habit: Property, Rights, and Numbers

Due diligence is the repeatable habit of verifying three things before you commit: (1) the property (its physical condition and systems), (2) the rights (what you can legally own/use and whether boundaries match what you think you’re buying), and (3) the numbers (costs, risks, and obligations that change your true all-in price). The goal is not to “find a perfect property.” The goal is to reduce surprises and convert unknowns into either (a) acceptable risks, (b) negotiated repairs/credits, or (c) deal-breakers.

A simple workflow you can reuse

1. Screen: quick checks before spending money (disclosures, obvious red flags, basic hazard map lookups, initial rent roll/lease summary if applicable).
2. Investigate: inspections, document review, and third-party reports (survey, insurance quotes, permit history).
3. Quantify: translate findings into dollars and decision points (repair budget, insurance premium, compliance costs, vacancy risk).
4. Decide: proceed, renegotiate, or walk—based on written criteria you set in advance.

1) Property Condition: What Inspections Should Actually Cover

A property can “look fine” and still hide expensive issues. Inspections are about systems, moisture, safety, and remaining useful life. Even if you hire professionals, you should know the themes so you can ask better questions and interpret results.

Inspection themes (what to verify)

• Structure & foundation: cracks (type and movement), uneven floors, doors/windows out of square, drainage around the home, signs of settling.
• Roof & exterior envelope: roof age and layers, flashing, gutters/downspouts, siding condition, window seals, caulking, grading and water management.
• Water intrusion & moisture: basement/crawlspace dampness, staining, musty odors, efflorescence, sump pump function, attic ventilation, bathroom/kitchen exhaust.
• Plumbing: supply line material, water pressure, drain performance, water heater age, visible leaks, sewer line risk (especially older homes or lots with large trees).
• Electrical: panel capacity and condition, aluminum wiring (where relevant), GFCI/AFCI presence, DIY wiring signs, grounding/bonding, number of outlets and load concerns.
• HVAC: age, service history, duct condition, heat/cool performance, refrigerant type (older systems), thermostat zones, combustion safety.
• Safety & environmental: smoke/CO detectors, handrails, trip hazards, potential lead paint/asbestos (age-dependent), radon (area-dependent), pest/termite activity.
• Site & drainage: slope away from structure, standing water, retaining walls, driveway condition, tree proximity to roof/sewer, erosion.

Practical step-by-step: how to run the inspection phase

1. Book the general inspection early so you have time to follow up with specialists.
2. Attend the inspection and ask the inspector to show you the top 5 cost drivers and top 5 safety issues.
3. Trigger specialist inspections based on findings (examples: roofer, structural engineer, sewer scope, electrician, HVAC tech, pest/termite, mold/moisture specialist).
4. Convert findings into a repair plan: immediate safety fixes, near-term replacements (1–3 years), and longer-term capital items.
5. Price the plan using written bids or realistic allowances; avoid “hand-wavy” estimates for big-ticket items.
6. Decide your negotiation approach: request repairs, request a credit, adjust price, or walk if risk is unacceptable.

2) Title and Boundary Checks: Making Sure the “Box” Matches Reality

Even when a seller is honest, paperwork and reality can diverge. Title and boundary checks confirm you can receive clear ownership and that the physical property you think you’re buying matches legal descriptions and recorded rights.

Title basics to verify (through your closing professional)

• Ownership chain and authority: the seller has the legal right to sell (watch for estates, divorces, entity authority issues).
• Liens and judgments: mortgages, tax liens, mechanic’s liens, HOA liens, or other claims that must be cleared.
• Easements: utility easements, shared driveways, access easements—these can limit building or affect privacy/use.
• CC&Rs/HOA rules: restrictions that affect rentals, parking, exterior changes, pets, short-term rentals, etc.
• Encroachments: fences, sheds, driveways, or additions crossing boundaries or violating setbacks.

Survey concept (boundary check in plain language)

A survey is a professional measurement that maps the property boundaries and shows improvements (house, fence, driveway) relative to those boundaries and to recorded easements/setbacks. Think of it as verifying the “shape and edges” of what you’re buying.

Practical step-by-step: boundary and title verification

1. Order title work and read the title commitment/report: focus on exceptions (easements, restrictions, unresolved items).
2. Ask: do I need a new survey? Common triggers: unclear fences, shared driveways, additions near lot lines, vacant land, rural property, or any boundary dispute hints.
3. Review the survey with the title exceptions: confirm easements shown match recorded documents; look for encroachments.
4. Confirm legal access: the property must have legal, recorded access to a public road (especially important for rural or flag lots).
5. Resolve issues before closing: boundary agreements, releases, endorsements, or seller cures—don’t “assume it will be fine later.”

3) Occupancy and Lease Review Basics: Who Has the Right to Be There?

Occupancy affects your timeline, costs, and legal obligations. A vacant home, an owner-occupied home, and a tenant-occupied property each carry different risks and required verifications.

What to verify for occupancy

• Current status: vacant, owner-occupied, tenant-occupied, or mixed.
• Move-out/possession terms: when you can take possession and what happens if the seller/tenant doesn’t leave on time.
• Condition vs. occupancy: occupied properties can hide deferred maintenance; vacant properties can hide freeze damage or vandalism issues.

Lease review basics (for rentals)

• Lease documents: signed lease, addenda, renewals, notices, and any side agreements.
• Key economics: rent amount, due date, term, renewal options, late fees, utilities responsibility, concessions.
• Deposits: amount held, where held, and transfer process at closing.
• Tenant ledger: payment history, delinquencies, fees, credits.
• Rules that affect operations: pets, smoking, parking, maintenance responsibilities, yard care, subletting.
• Compliance: required disclosures (varies by location), habitability obligations, and any local registration requirements.

Practical step-by-step: verifying leases and occupancy

1. Request a lease packet for each unit/tenant (lease + addenda + ledger + deposit info).
2. Compare listing claims to documents: rent, term, utilities, and included appliances must match the lease.
3. Confirm deposits and prepaid rent: ensure they will be credited/transferred at closing.
4. Estoppel (when possible): have tenants confirm key lease terms in writing (rent, deposit, term, any promises).
5. Walk the unit(s): verify occupancy, condition, and any unapproved occupants/pets.

4) Insurance and Hazard Awareness: Pricing the “What If”

Insurance is not just a checkbox; it is a pricing signal about risk. Some hazards also affect financing, repair requirements, and resale.

Hazard concepts to understand

• Flood zones: properties in certain zones may require flood insurance; even outside mapped zones, localized flooding can occur.
• Wildfire/brush risk: can raise premiums, increase deductibles, or limit insurer options; defensible space may be required.
• Wind/hail risk: may drive roof requirements and special deductibles.
• Earthquake risk: often excluded from standard policies; optional coverage may be costly.
• Water damage: a common claim source; some policies limit certain water losses.

Practical step-by-step: insurance and hazard verification

1. Get insurance quotes early using the actual address and property details (age of roof, wiring type, prior claims if known).
2. Check hazard maps (flood, fire risk where available) and compare with what insurers ask for.
3. Ask about exclusions and deductibles: wind/hail, water backup, wildfire, etc.
4. Budget for mitigation: examples include roof replacement, tree trimming, sump pump/backup, defensible space, or drainage improvements.
5. Confirm insurability: if you can’t obtain acceptable coverage at a workable price, the deal may not be financeable or prudent.

5) Regulatory Checks: Zoning, Conformity, and Permits

Regulatory due diligence verifies the property’s current use is allowed and that past work was properly approved. Problems here can force expensive corrections or limit future plans (adding a unit, finishing a basement, running a home business, renting short-term, etc.).

What to verify

• Zoning conformity: the current use matches zoning (single-family, duplex, accessory unit, etc.).
• Nonconforming status: if the property is “legal nonconforming,” changes or rebuilding after damage may be restricted.
• Permits and final approvals: major work (roof, electrical, plumbing, additions, structural changes) should have permits and final sign-offs when required.
• Open permits: unfinished or unclosed permits can become your problem.
• Rental regulations: licensing, inspections, occupancy limits, or registration requirements (especially for small rentals).
• HOA/municipal rules: parking, exterior changes, fencing, short-term rental bans, noise rules.

Practical step-by-step: regulatory verification

1. State your intended use (live-in, long-term rental, add ADU, etc.) and verify it’s allowed.
2. Check zoning and overlays (historic district, floodplain overlay, wildfire interface, etc.).
3. Pull permit history from the local building department (online portals are common).
4. Match permits to what you see: if there’s a finished basement or converted garage, confirm it was approved.
5. Identify cure paths: if something is unpermitted, ask what it would take to legalize (inspection openings, engineering letters, fees).

Practical Due Diligence Checklist (Organized by Category)

Use this as a working checklist. Mark each item as Done, In progress, Not applicable, or Red flag, and add notes and dollar estimates.

Apply the Checklist: Scenario A — Starter Home Purchase (Owner-Occupied)

Situation: You’re buying a starter home to live in. Your main risks are unexpected repair costs, inability to insure/finance, and surprises that affect safety and livability.

How to apply (step-by-step)

1. Property condition first: prioritize roof, foundation, moisture, electrical safety, and HVAC reliability. These affect comfort and immediate cash needs.
2. Insurance quote early: owner-occupied policies can still spike due to roof age, claims history, or hazard exposure. Confirm you can obtain coverage before you’re locked in.
3. Title and boundary check: confirm no liens and understand any easements (utility easement across backyard, shared driveway). For a starter home, a survey is especially valuable if fences, sheds, or driveways are near lot lines.
4. Regulatory check focused on safety and future plans: verify permits for major renovations you can see (finished basement, deck, electrical panel upgrade). If you plan to add a fence, shed, or remodel, confirm zoning/HOA rules.
5. Quantify repairs into a move-in budget: separate “must-do before move-in” from “can wait.”

What differs in this scenario (and why)

• Lease review is usually not applicable because you’re taking personal possession. The key occupancy check is possession timing (when you get the keys) and ensuring the home will be delivered as agreed.
• Livability and safety carry extra weight: a marginal HVAC system or electrical hazards matter more when you must live there immediately.
• Future flexibility matters: zoning/HOA restrictions on additions, parking, or home-based uses may affect your plans and resale appeal.

Example decision translation

If the inspection shows an aging roof and minor plumbing leaks, you might negotiate a credit and proceed. If it shows chronic basement water intrusion with unclear cause, you might require specialist evaluation and a drainage plan (with bids) before removing contingencies.

Apply the Checklist: Scenario B — Small Rental Purchase (Tenant-Occupied)

Situation: You’re buying a small rental (single-family rental or small multifamily). Your main risks expand to include tenant rights, lease enforceability, rent collectability, compliance with rental rules, and insurance suited to a landlord.

How to apply (step-by-step)

1. Start with occupancy and leases: request the full lease packet immediately. Verify rent, term, deposits, utilities, and any concessions. The property’s “income story” must match documents.
2. Confirm tenant status and possession rules: understand whether you can raise rent, when leases expire, and what notice rules apply. Your timeline is constrained by lease terms and local law.
3. Property condition with a landlord lens: focus on durability and code/safety compliance (handrails, smoke/CO detectors, egress where required). Deferred maintenance becomes your operational risk.
4. Insurance quote as a landlord policy: premiums and coverage differ from owner-occupied. Confirm liability coverage and any requirements tied to roof, wiring, or hazard zones.
5. Regulatory checks expand: verify rental licensing/registration, inspection requirements, occupancy limits, and whether the unit configuration is legally recognized (especially if it’s a converted duplex or has an accessory unit).
6. Quantify “stabilization costs”: include repairs, compliance upgrades, potential vacancy/turnover costs, and reserves for capital items.

What differs in this scenario (and why)

• Lease verification becomes central: your cash flow depends on enforceable leases, accurate deposits, and realistic rent assumptions. A “market rent” claim is irrelevant if the lease locks in a lower rent for months.
• Regulatory risk is higher: rentals may require licenses, inspections, or specific safety features. An unpermitted unit can mean forced deconversion or expensive legalization.
• Insurance and liability stakes increase: tenants and visitors raise liability exposure; certain hazards or property conditions can make landlord coverage expensive or unavailable.
• Possession is not immediate: you inherit occupants and their rights. Your renovation plans may need to wait until lawful vacancy.

Example decision translation

If leases are month-to-month with inconsistent payment history, you may budget higher vacancy/turnover and require stronger documentation (ledger, estoppel) before proceeding. If the property is advertised as a duplex but zoning/permits indicate single-family, treat it as a major red flag until verified and priced as-is.
