Look at 3br/1ba houses vs 3br/2ba houses and quantify the difference the extra bath makes in price.  

I am working on trying to put together a deal on a multi family building and wanted to get some feedback on how much extra I can pay for a property in exchange for receiving seller financing.

i buy my properties in rochester ny now with buying the new 4 extra property i should be  making 6000 a month but will own 50,000 in credit card now that i use credit for buying 4 houses cash

I understand your strategy to be able to pocket extra money, but if my end game is to own several multis i feel like it would be retroactive to sell it after i went through the pain, and exhaustion of a full rehab. 

However, others are not like that and need that extra firmness.

@Gary KuhnThis is interesting from a management perspective, we charge investors a small fee to maintain an administrative account for their tenant because there is some extra administrative work when there are additional occupants.

Additionally, once I have the loan pressure is on to take the first offer I’m given because of the daily interest costs on the loan, I’ve lost out on an extra $30k on one deal because I pulled the trigger 10 days too early on an offer.I’ve tried to present bankers an offer to fund the loan but I haven’t found the right “combination” as Brandon Turner likes to call it.  

Extra work/risk => extra reward.

However, it's extremely important to note that you CANNOT take the extra concessions as cash.

Then house hack by renting out the extra bedrooms.
