/ Free tool · Section 24 landlord tax
What does Section 24 cost you?
Mortgage interest is no longer deducted from rental income, it gets a 20% credit instead. PropSnap shows your real tax and net profit, and the extra Section 24 has added. Instant, in your browser, on 2025/26 rates.
Local estimate
Section 24: mortgage interest is not deducted from rental income; a 20% basic-rate tax credit applies instead. Estimate for an individual landlord on 2025/26 rates; the credit is subject to HMRC caps and this ignores the personal-allowance interaction. Not tax advice.

/ FAQ · before you ask
What people ask before they use PropSnap.
01 Is the viability number lender-grade? +
Indicative. Final viability needs a chartered QS and an RICS Red Book valuation. PropSnap gets you to the right number to start the conversation.
02 Does it cover commercial-to-residential conversions? +
Yes, Permitted Development rights (Class MA, Class AA, Class O) are dedicated tracks.
03 Will it handle Section 106 and Community Infrastructure Levy? +
Yes, both are surfaced against the local authority's published rates.
04 Is the planning probability legally meaningful? +
No, only a planning officer's decision is. The probability is a screen based on LPA approval patterns, design-officer signals and policy fit.
