Okay I got stuck at the loan part. 

ARV: 290k, if property was purchased at $215, $30 rehab (overestimating it), taxes are $92 a month. Would rent for $1600 a month. I have not tried to get hard money loans yet or personal so I am taking examples of what i've seen others use to just run these reports and get better at it. But for the amortization of the first loan (which would be a private/ hard money loan), wouldn't the amortization be in months? I used 3.5 as the points. I put 30 years and that isn't right. I would want to do a 3 or 6 month loan and then quickly refinance to a 2.99 30 year loan at 75% LTV. So how do I adjust the numbers? TIA!!! Newbie and just trying to get better at looking at things!
