Valuation
A cap rate is a price, not a return.
Cap rate is NOI divided by price. It says what the market pays for a dollar of income today. It says nothing about leverage, appreciation or what you will actually earn. Those live in cash-on-cash and IRR.
Small moves in cap rate are large moves in value:
NOI $300,000
@ 6.00% cap $5,000,000
@ 6.50% cap $4,615,385
50 bp move –$384,615
Operations
Every dollar of NOI has a multiplier.
At a 6.25% cap rate, each $1 of annual NOI is worth $16 of value (1 ÷ 0.0625). Cutting $5,000 of recurring expense adds about $80,000 to what the building is worth.
That is why I start sell-side work with an expense audit: tax abatement eligibility, insurance re-bids, utility billing (RUBS or submetering where allowed), and service contracts nobody has re-bid in years.
Tax timing
The 1031 clock starts at closing.
In a §1031 exchange you have 45 days from the sale to identify replacement property in writing, and 180 days (or your tax return due date, if earlier) to close on it. A qualified intermediary must hold the proceeds.
The planning happens before the listing: a realistic replacement pool, lender pre-approval, and a sale date chosen around the calendar.
Tax exposure
Know your recapture before you price.
Residential rental buildings depreciate over 27.5 years, nonresidential over 39. On sale, the depreciation you took is generally taxed as unrecaptured §1250 gain at up to 25%, separate from capital gains.
A long-held building with a low basis may net far less than its price suggests. That changes whether you sell, exchange, refinance or hold.
Structure
Draw the entity map before the next deal.
Before adding a property, look at how everything is already held:
- Liability: which assets share exposure if one has a claim.
- Lending: moving title into an LLC after closing can conflict with the mortgage's transfer clause. Check first.
- Title insurance: confirm coverage carries over when title changes hands.
- Exit: a 1031 generally needs the same taxpayer on both sides.
Massachusetts diligence
The state-specific items that change a deal.
- Title 5: septic inspection at transfer for properties not on sewer, and septic capacity can cap density on small lots.
- Lead Law: pre-1978 rentals with a child under 6 require deleading. Know the compliance status before you price.
- Smoke & CO: a fire department certificate is required before transfer.
- Chapter 21E: environmental history on commercial and mixed-use sites, including old fuel tanks.
- Fire protection on conversions: adding units or changing a building’s use, such as a single-family to multifamily or a church or commercial building to housing, can trigger sprinkler and fire alarm requirements under the state building code and local fire department rules, including a master fire alarm box tied to the town’s system. Price this in early; it can decide whether a conversion works.
- Millionaires Tax: Massachusetts adds a 4% surtax on taxable income above $1,107,750 (2026, adjusted yearly), and capital gains count. A single large sale can push an owner over that line, so sale timing, installment terms or a 1031 exchange are worth planning with your CPA.
