alright nathan i will be the first, but surely not the last on this one... First and foremost, unless you have HORRIBLE credit that 9% is way too much with 20% down.
now for the basics...
Purchase price $36,000
down payemnt $7200
financed $28,800
monthly payment $293
insurance/taxes about another $100
lets figure $400 a month for all this
total rents $700 per month x .60 (assuming you are going to manage the property)= $420 - $400 for mortgage payment = $20 cash flow per month...
now the norm that people seem to shoot for is $100 per door, so you are about $180 short of that. So you will either have to increase rent to about $500 per month or lower the price down, or get a better interest rate or get a 30 year or 40 year mortgage.....
And finally your last problem, which might be your toughest hurdle (as i had this problem) Unless you are in good with your banker you will be hard pressed to find anyone to give you funding for such a low amount
