First mortgage checklist: payment, deposit, fees — in order

Do not start with the maximum bank quote. Start with a payment you can live with.

Rank by rate and cash-flow pain — then avalanche or snowball.

Emergency fund: how many months and where to hold it

Must-haves before any loan.

Compare debt interest to real investment return.

4% is a rule of thumb — verify your costs.

How to verify calculator results

Two scenarios, one parameter, one official source.

Gig income: convert a good week without lying to yourself

Peak weeks are not a salary. Annualize with quiet weeks included.

BNPL and cashflow: free is not free if timing breaks

Stacking “pay in 4” plans is just fragmented debt with better UX.
