Can rent be added to your salary when applying for a mortgage?
I can answer Scenario #3. If you are purchasing a property with buy-to-let intentions […] can you use the   rental income exclusively to fund the mortgage repayments? Yes – this is exactly how buy-to-let mortgage applications are evaluated. Lenders generally expect you to fund the mortgage payments with rent. They look for the anticipated monthly rent income to cover a minimum of 125% of the monthly mortgage payment. This is to make sure you can allow for vacant periods, maintenance, compliance with rules and regulations, and still be in profit (i.e. generate a positive yield on your investment). However, buy-to-let (BTL) mortgage lenders also generally expect you to own your own home to begin with. It's up to them, but rare is the lender who will provide a buy-to-let mortgage to a non-owner-occupier. This is because of point 2 above. The lender doesn't want you to end up living in the property because then you'll need to repay the loan capital, since you'll always need somewhere to live. This makes the economics of BTL unfavourable. They look at your application as a business proposal: quite different to a residential mortgage application, which is what your question seems to be addressing. Bottom line: You're right about scenario #3 but it sounds like you're trying to afford a home first, whereas BTL is best viewed as an investment for someone who already has their main residence under ownership (mortgaged or otherwise). As for Scenarios #1 and #2 I can't offer first hand answers but I think Aakash M. and Steve Melnikoff have covered it.
