Does the property cover itself?

DSCR calculator

On a DSCR loan the property qualifies, not you. The whole underwrite comes down to one ratio — and to a detail nobody mentions until it costs you: whether vacancy is deducted before it is worked out.

A coverage ratio is two numbers on the day you sign. It knows nothing about a boiler, a void month, or a letting agent's fee, and it is not a measure of whether the property is a good investment.

Your inputs

The property

DSCR programmes usually want 20% to 25%, and price better the further above that you go.

Carrying it

The rent

Usually the lower of a signed lease and the appraiser's rent schedule.

Set it to what your lender actually applies. Most apply none — which is why the ratio looks better than the property does.

What PITIA is made of
Ratio against rent

The dashed line is 1.00 — where the rent exactly covers the payment. Programme tiers usually sit at 1.00, 1.15 and 1.25.

Take this with you

Every number you entered is in the address bar. Copy the link and it opens with your inputs restored — that is how everything else here shares.

Nothing is sent from this site. This is a demonstration: when you press the button it builds a message you can send yourself from your own mail app, which is the only honest version of this feature here.

What this assumes

  • DSCR is qualifying rent divided by principal, interest, taxes, insurance and association dues. Nothing else enters it.
  • Vacancy is applied to the rent before the division, if you set one. Whether your lender does is a question worth asking in writing.
  • Taxes and insurance are the figures you typed. Insurance on a let property is not the same product as owner-occupier cover, and is usually dearer.
  • No maintenance, no management fee, no capital expenditure, no void periods. The lender's ratio ignores all four, and so does this — which is exactly why it should not be the only number you look at.
  • An interest-only start would raise the ratio substantially while it lasts and is not modelled.

Have someone look at it

If this were a working site, this is where the conversation would start.

Only used to call you back — and on this demonstration, not even that.

This form does not send anything. It validates what you type, shows you a confirmation, and stops there. Nothing is stored, nothing is transmitted, and nobody will call you. There is no consent box here because there is nothing to consent to.
