You invest in properties.Do you know what they return?

Return on equity, gross yield, return on cash and total return for every property, accrued month by month from the cash that actually moved.

• Accrued, not annualised

  Most tools multiply one month by twelve. Welfyn adds up what happened, so a void or a boiler shows in the figure.

• From the purchase, not from sign-up

  Give it the price, the debt and the month you bought, and the capital story plots from day one.

• One property or the whole portfolio

  Every asset on its own ledger, and all of them pooled into one, with the same maths at both scopes.

Every transaction arrives already read: matched to the right property, labelled, deduplicated and reconciled each day, without a spreadsheet to keep up.

• Categorised on arrival

  Rent, mortgage, repairs and insurance are labelled as they land, and anything uncertain is set aside for a one-tap review.

• Matched to the property

  One account can serve several properties. Each payment finds the asset it belongs to.

• Statements work too

  Prefer to keep banking separate? Upload a statement and Welfyn reads it the same way.

A built-in analyst that answers plain-English questions about your own portfolio, and shows the working behind every figure it gives you.

• Plain English in, a figure out

  What did this flat cost to run last year? Which property is working hardest? Ask the way you would ask an accountant.

• The working, every time

  Every answer names the transactions it was built from, so you can check it rather than trust it.

• Your data only

  It reads your ledger and nothing else. It cannot see other users, and it does not give financial advice.
