I'm going to lay out the bare facts and see what others think.
We are in our mid-50's with one young teen. £100k on mortgage, costing £1k per month. Generally save £500-£1000 per month.
Pensions not great for various reasons so have stepped these up massively in the last year. Likely looking at 100k in each by retirement.
We have 50k towards an extension (inheritence). To do what is planned will mean adding 40k to the mortgage. This will = £400 per month.
Plan is to host foreign students. On paper we can afford the mortgage but income from students would give us extra security and savings.
This was all ready to book in the diary two weeks ago but the world is a different place now.
So my question is, would you look at adding that sort of burden to your finances when the price of the build is likely to go up and general costs will squeeze us into needing the income from students?
Other ibfluencing factors: young teen has ASD so I can't guarentee he will take to students, could love it, could hate it; both cars are 15+ and plan was to only replace one: if we need student income, we'll need two cars.
