Hello, does anyone have experience of trying to get a mortgage on a property based on the income (guesthouse) from that property?

I am looking at farmhouse type properties that need some restoration work, which I will undertake bit by bit. Therefore I need to look at interest only nmortgages for the short-term, relying on my savings to pay the repayments until the property is ready to rent.

If I move to Morocco for say 6 months to be with my partner, with the intention of starting a business and getting the property ready what bearing will this have on obtaining a mortgage?

Any advice gratefully received.
