makes sense. so i actually did a 2-1 buydown FHA, i have a 800 credit score and locked in a 5.875% in today's market which is pretty damn good IMO... so the first year ill be at a 3.875% with about a $2350 monthly payment including prop tax/pmi/morg insurance/home owners insurance. lease is locked in for a year at $1400 a month which makes me only have to pocket roughly $1000. the way i see it, its cheaper than rent or mortgages in today's world!...
