It's scary I was talking to a lady at work who couldn't understand why her husband was balking at the prospect of a 700k mortgage...
We have 2 properties and totally mortgage for both would be 3 times our combined income but we get rent for one so that changes things a lot. We don't rely on the tenants rent as a given we are realistic that at times they will be late in paying or the property could be vacant at times so we can still cope well.
