Hello guys I have enough money to buy a house with cash, however I don't want to do that. I was asking lenders if they offer low-doc mortgage but they don't anymore. So a friend suggests I can just buy it with cash and couple months later I can refinance it and get like 80% of the money out? my question is if I do this way is the interest rate higher then the regular loan mortgage or the same, wha'ts the difference between the 2, is it 30 years fixed rate? and how much can I take out can I take out 100%? how soon can I refinance it, a week after I bought the house? 2 months?I can't find much info on this online can someone point me to a website about this? thanks a lot
