STOP!
PLEASE for your own financial future, STOP this now! This is beyond insane, I cannot believe you are even contemplating doing this!
Let's quickly distil the facts, please tell me if I miss anything/ make any mistakes:
- You are buying a 3 bedroom warehouse conversion in 'not in the nicest part of town (not the worst, but hasn't got the greatest reputation)' part of SE London
- You are hoping to pay £540,000
- You are on a 2 year fixed I/O mortgage
- You are going to rent out the third bedroom for £x? a month
- You have a 30% deposit and your mate's mum is guaranteeing the mortgage
- Your mate earns 18,000 per year so has around £1,200 take home?
So tell me the following:
1) What happens if house prices go down?
2) What happens if interest rates are 4% (Still low by historical standards, but 8x higher than now) by the time your mortgage fixed term ends in 2 years?
3) What percentage of the property will you have paid off over that period?
4) What happens if you and your mate fall out?
5) What happens if one or both of you lose your jobs?
6) Can you afford to have the third room empty?
7) After 2 years when you need a new mortgage deal, are you going to find someone to take you on given IR's will probably be higher?
8) Can you afford to start paying this off after two years even if interest rates are a mere 2%?
So you are entering an agreement to take on £540,000 (Minus deposit) of debt against an asset that has a fair chance of
falling in value over the next year or two.
After two years, you will have spent £900 per month on servicing a debt you have not paid one single penny against, which is still tied to an asset that might be worth less than it is now. i.e.
IN THIS CASE, YOU WILL PROBABLY NOT BE ABLE TO AFFORD TO SELL IT
In two years time, you will need a new mortgage and interest rates are pretty much guaranteed to be higher than they are now.
Will you be able to get a new deal? afford even IO? be able to pay off this debt? or is it going to be IO for ever?
You do realise if one of you want out, you cannot simply have the mortgage transferred into one person's name, you need to effectively sell the place or 'buy out' their half? You are effectively married to this guy in a financial sense.
Renting from the bank whilst accepting a liability of over half a million pounds and blowing away a MASSIVE deposit is just
mad- never mind an FA or bank manager, you need to see a doctor if you think what you are doing is financially sound in any way, shape, or form.
