What a Maryland Overlap Actually Costs
Program and regulatory figures verified September 25, 2026. Details change; confirm your scenario with us.
Maryland has two costs most states do not. Price them first, because together they often decide which structure you should be using.
Step one: the recordation tax, if you borrow
Only one structure triggers it. If you record a second mortgage or equity line against the departing home, Md. Tax-Property 12-108(e) taxes the increase in unpaid outstanding principal debt. If you refinance, 12-108(g) shelters you up to the unpaid principal of the loan being refinanced, so only the excess is taxed.
Rates are set by each county and Baltimore City. Take the amount of new money, multiply by your county's rate, and that is a real closing cost on a loan you plan to hold for weeks. Carrying both payments or renting the home out records nothing and costs nothing here.
Step two: the new home's taxes, uncapped
Do not use the seller's bill. Md. Tax-Property 9-105 withholds the Homestead Tax Credit for a taxable year where the dwelling was transferred for consideration to new ownership in the previous taxable year, so the seller's capped taxable assessment does not follow the house.
Take the current assessment, apply your county's rate, and use that in the payment. Then file your own homestead application by June 30 for the following taxable year so the cap starts building for you.
Step three: the rental offset, if you keep it
Under Fannie Mae B3-3.8-05, take monthly gross market rent, multiply by 75%, subtract the departing PITIA. Positive offsets that property's payment and nothing more. Negative is added to your debt-to-income ratio.
Build that PITIA with the departing home's tax line after it loses its own homestead credit, since a tenanted home fails the more-than-6-months occupancy test in 9-105(a)(5)(i)(1).
Step four: reserves
With less than 12 months of property management experience, six months of the vacated home's PITIA, in addition to reserves required for multiple financed properties. Bridge structures separately tier reserves against marketing time, and Maryland's largest markets were flat in August 2026.
And the ceiling
Check the county limit before any of this: $832,750 in 19 Maryland jurisdictions, $1,249,125 in Montgomery, Prince George's, Frederick and Charles, and $1,209,750 in Calvert. See the jumbo page, the structures page and the homestead reset page.
Frequently asked questions
How do I estimate Maryland recordation tax on a second mortgage?
Take the amount by which your unpaid outstanding principal debt increases and apply the recordation tax rate for the county or Baltimore City where the property sits. Md. Tax-Property 12-108(e) taxes a supplemental instrument to the extent of that increase; rates are set locally.
Should I use the seller's tax bill to budget my Maryland payment?
No. Md. Tax-Property 9-105 withholds the Homestead Tax Credit for a taxable year where the dwelling was transferred for consideration to new ownership in the previous taxable year, so the seller's capped assessment does not carry over. Use the current assessment.
What reserves should I plan for on a Maryland move-up?
For a rental conversion with less than 12 months of property management experience, six months of the vacated property's PITIA, plus any reserves for multiple financed properties. Bridge structures separately tier reserves against local marketing time.
