Investment deals fail on assumptions, not on price. A property that pencils at a glance can lose money the moment a real renovation scope, a real vacancy assumption, or a real insurance quote replaces the placeholder in the spreadsheet.
Start with the exit, not the entry
Decide before you underwrite whether the property is a long-term hold, a value-add refinance, or a resale. Each demands a different purchase price, different renovation scope, and a different tolerance for timeline risk. Buying first and choosing a strategy later is the most common and most expensive mistake.
The underwriting checklist
- Verified rents from actual leases, not from listing-site estimates
- Renovation scope priced from a contractor walkthrough, with a contingency for what opens up behind the walls
- Taxes based on the post-sale assessment, not the seller's current bill
- Insurance quoted for the actual property — coastal and older-construction premiums vary widely on the North Shore
- Realistic vacancy, turnover, and capital reserves
- Zoning, permit history, and legal unit count verified with the municipality
- Utilities: which are separated, which are the owner's, and what separating them would cost
Costs that get left out
- Holding costs across the full permit-to-completion timeline, not the optimistic one
- Lead paint compliance in pre-1978 housing
- Deferred exterior work — roof, siding, windows, drainage — that inspection reveals but the pro forma ignores
- Municipal requirements at transfer, such as smoke and carbon monoxide certification
- Financing costs and points on renovation or bridge debt
Older housing stock is the local variable
Much of Essex County's inventory is decades or centuries old. That means knob-and-tube, undersized services, mixed additions, and framing that doesn't match any plan on file. Underwriting that treats these buildings like new construction is underwriting a different property.
We evaluate deals with construction and development experience on the same side of the table — scope, cost, and timeline reviewed before the offer, not discovered after the closing.
