“Everyone is not like you being such a shrewed investor”
Not for me to say one way or other.
“and expert in the whole Spainsh property market”

“thats why people ask questions on the forum”
OK, so if not an expert, read the experts. One such the weekend states that in the buy to let market, you need a rental yield of 7% to service the loan. Therefore, if self funding, you probably need 6.5% to tread water.
