Hassan,
I too enjoy this thread, very informative and chocked full of reality.
One issue that I would like to clarify is your calculations for purchase price (MAO).
In my part of the country you would not get many deals AT ALL using this formula. An average of the numbers posted above shows that you are typically buying at 30% of ARV. That's great if you can find deals like that all day, however, realistically you are leaving a lot of stones unturned.
A recent example of one of my rehabs:
ARV 90K - 95K, purchased at 61K with 5K repairs.
After HML financing = 66K
Holding costs/misc = 3.5K
Repairs = 5K
Total = 74.5K
Sell for 93K
Net after commissions, closing costs = 84.4K
Net gain = ~10K
I typically use the 65% of ARV minus repairs to arrive at my MAO. According to my formula I should have paid 53.5K but the risk was low so I went for it anyways.
Now, this was a slim deal compared to most that I do, but, is an easy 10K something that you would pass up. I performed a rough calculation your way, MAO of ~32K. Around here, other investors would out-bid you constantly, severely reducing your volume for the year.
Thanks for reading, this was just an issue that I thought could use some debate.
Maybe I'm moving to Georgia!
