In UK 5% mortgages are readily available to first time buyers. It's a completely normal thing here in UK. And I can assure you she doesn't have a lot of money and the mortgage wasn't cosigned by anyone else lol.
>>A good rule of thumb is to have at least 35% of the estimated cost.
Well now that's absolutely nuts. Here in UK 10% deposit is normal, 15% is high, and I don't know anyone who paid 20% or more - and everyone in my group of friends(we all just turned 30) bought a house recently.
>>The average UK price house is 256k
Yes, because London destroys the averages completely. Like I said, my sister just bought a 3 bed house with a garden and driveway for £150k, and it wasn't particularly cheap, neither for the street nor for the area .
