Three Ways to Buy Your Next Massachusetts Home First
Program and regulatory figures verified September 25, 2026. Details change; confirm your scenario with us.
The three structures are the same everywhere. Massachusetts adds one question the others do not: whether this is the year you want to realise the gain.
Carry both payments, then recast
You qualify carrying the current mortgage and the new one together, buy, and when the old home sells apply the proceeds to the new loan's principal and ask the servicer to recast. Recasting re-amortizes the remaining balance over the remaining term, lowering the payment without a refinance or new closing costs.
Cleanest structure when income supports both payments. The thing to size carefully is the principal reduction, because it comes from net proceeds, and in Massachusetts those proceeds may be competing with a surtax liability arising from the same sale. See the net proceeds page.
Borrow against the equity you already have
A closed-end second or an equity line against the departing residence converts trapped equity into a down payment, repaid from the sale at closing.
Massachusetts permits it. There is no state constitutional restriction of the kind Texas imposes, where Article XVI Section 50(a)(6) caps all homestead liens at 80% combined loan-to-value and prohibits a subordinate home equity line outright. The ceiling here is the investor's guideline.
The payoff still comes from the sale, so the same net-proceeds arithmetic applies.
Keep it and rent it
The departing home becomes a rental. There is no sale, which means no proceeds, and also no capital gain realised in that tax year.
On a Massachusetts home held for decades that second point can be significant, because mass.gov puts the 2026 surtax threshold at income exceeding $1,107,750, and a large gain above the federal exclusion flows into that year's taxable income. Not selling is the only structure that keeps the question closed for now.
We are not advising on that. Whether it helps, and what it defers rather than avoids, is a CPA question. What we can say is that it belongs in the comparison. See the surtax page and the rental conversion page.
The financing side changed in September 2026. Fannie Mae B3-3.8-05, dated 09/02/2026 under Announcement SEL-2026-08:
- No leases. Lease agreements are not permitted for any departing residence. Market rent comes from a complete appraisal with market rents, a Form 1007, or market analysis tools with at least three comparable rentals.
- Offset only. Gross rent times 75% less that property's PITIA. Positive offsets that payment; negative goes into the ratio.
- Reserves. Six months on the vacated home under 12 months of property management experience.
How the choice gets made in Massachusetts
| If this is true | Look first at |
|---|---|
| Income comfortably carries both payments | Carry and recast, sized on net proceeds |
| Equity is strong and the sale is weeks away | Borrow against it |
| You have owned the home for decades in an appreciating market | Ask your CPA about the gain before you choose anything |
| You are buying on the islands or in the Boston metro | The three tiers page, since the limit is not the baseline |

What this costs, and why we will not put a number on this page
Bridge-style financing prices above a first mortgage, and the real number is a function of your file. Here is what drives it.
Available equity in the home you are leaving, how long the two loans run alongside each other, and the structure. Massachusetts adds a consideration most states do not: the surtax on high incomes means a large gain on the departing home can land you somewhere you did not expect, which sometimes makes the timing of the sale worth more than the financing spread. That is a question for your CPA, and it changes which structure is cheapest overall.
Which is why we would rather talk it through than publish a figure. Send us the two properties and we will lay out the cost of each route.
Frequently asked questions
How much does buying before selling cost in Massachusetts?
Bridge-style financing prices above a first mortgage, and the figure depends on your equity, the overlap between the loans, and the structure you choose. In Massachusetts the timing of the sale can matter as much as the financing, because a large gain on the departing home interacts with the state surtax. That is a question for your CPA, and it can change which route is cheapest overall. We price the scenario rather than publishing a rate.
Which Massachusetts structure avoids realising a capital gain this year?
Keeping the departing home as a rental, because there is no sale. That is the only one of the three that does not put a gain into the current tax year, which matters where the 2026 surtax threshold of $1,107,750 is in play. Whether it helps your situation is a CPA question.
Does Massachusetts limit a second mortgage against my current home?
Massachusetts has no constitutional cap of the kind Texas imposes, where Article XVI Section 50(a)(6) caps all homestead liens at 80% combined loan-to-value and prohibits a subordinate home equity line. In Massachusetts the limit comes from investor guidelines.
How much rental income counts when I keep my old Massachusetts house?
Monthly gross rent times 75%, less that property's PITIA. A positive result offsets the departing residence's payment only and never adds qualifying income; a negative result is added to your debt-to-income ratio. Fannie Mae B3-3.8-05, dated 09/02/2026.
What is a mortgage recast?
A recast applies a lump sum to principal and re-amortizes the remaining balance over the remaining term, lowering the payment without a refinance or new closing costs. For a buyer who carried both payments, net proceeds from the departing home fund it. Servicer policies vary.
