The Somers (answer below) hit the nail on the head (no pun intended)...
The "After Repair Value", a.k.a. "ARV" - is important to know. And if you are going to be getting an ARV loan, then lender is going to want to make sure the ARV ratio is also in balance.
There are certain ratios that are used (your Realtor and/or lender should advise you on this)..
Best of Luck,
