Stephen,
The idea of requiring a 20% return on any investment sounds nice but to me it doesnt seem like it would apply to all situations. What would you do with the following choice.
Option 1: Purchase and rehab on one house will cost 100k and return a 19k profit.
Option 2: A group of 4 homes will cost 100k for puchase and rehab and return 20k.
According to your 20% return requirement option #2 is acceptable but option #1 is not. The 20% return requirement is not taking into account that your probably putting in 4 times the effort to get that extra 1% return.
Am I missing something?
With that being said, here are the numbers i've come up with regarding the deal at hand. They are 3 duplexes that rent for $475/unit. These numbers are based on 1 duplex
85000: After Repair Value
-400: Inspection Costs
-800: Title Company closing costs(Buy side)
-5100: Realtor commissions
-800: Title Company closing cost (sell side)
-3000: Repair costs
+$7,410: Net Rental Income(65% of gross income for 4 month hold time)
-20,000:Desired profit
=$62,310 Max Purchase Price
Advice?
