Thanks everybody for the input.
It seems that may be it is better for us to rent for 6 months and look for a house slowly, so
we can see what area we like (either Marlow, Windsor, Richmond or else).
We are thinking on paying the same we pay here is SF, around 1200 pounds a month (approx 2100$),
for a 2 bedroom house or flat with furniture (ours will be in a storage here, waiting for shipping).
I will honestly would love to live in London, since I love noise (this are my Latino roots talking), people around,
diversity, shops, culture activities, music events, but London is out of our limits to buy (I want a house with garden, 3 bedrooms
and a BIG kitchen and I am not Kate Winslet or Madonna).
So instead on London I would like a town which can offer a little bit of what I mentioned above.
DH also has kept a Natwest account in UK for years, do you think it will help us with the credit record?
I did not know buying a house here was so complicated.
