Kostas,
I think you’re talking about ARV (After Repaired Value), am I correct?
If so, you’re also wanting to buy at 50% ARV?
In that case, you want to take the repaired value of the property, multiply that amount by 50% (or divide by 2) and then you’ve got your base figure. Then you subtract the costs of the rehab from that.
For example, let’s look at the following…
$100,000 ARV (after repaired value based on similar comps)
less “50%” discount <$50,000>
equals $50,000
less repairs $2,000
equals your maximum acceptable price/offer, or $48,000.
This last figure represents a purchase at 50% of ARV including repair costs.
BTW, the nicer/newer the neighborhood, the more competition there’ll be and the lower the discounts generally. However, my limit is 70% of ARV, less repairs. This way I’ve got plenty of room for hiccups and failed escrows, etc. regardless of the location.
Also, I would be very careful to account for the average number of days on market for your farm area. If things are NOT selling fast, your carrying costs are necessarily going to be higher. The other important thing to account for is the actual numbers of comps you find. If you’re not finding at least 3 comps that fall within 10% over and above the subject property’s lot size and square feet of living space and transfer dates that fall within the last 90 days, it means not much is selling in your farm that fits what you’re intending to flip and/or there’s not much demand for your size/location of product.
You have to take these factors into consideration, unless you want to turn your real estate business into the casino business!
As far as P.I. is concerned, this is your principal and interest earned/paid on a loan itself, and has no bearing on the purchase/sale price. Of course the bank cares what the PI is in relationship to your income level… and will set a limit on “loan to value” in every case.
Hope that helps! Have fun!
