This makes the selling price $300k higher than the numbers you would get from calculating the price based on a potential buyer's expenses.

( I assume there will be an appraisal in there somewhere or again, only the buyer gets burnt if your guesstimate at final value is wrong.)Should the end buyer pay half of of what the net would be?

Everyone is hunting for a good deal, get it and you won't have to worry about anything else :).  

When it comes to wholesaling, what sort of criteria are cash buyers looking for?  

Not familiar with PA contracts but I’ve never seen a requirement where the buyer Had to supply even inspection reports, let alone appraisals unless there was s appraisal clause you were taking advantage of.

Aaron Hunt thanks for the info!

Most of the multi families I’ve lost this past year have been to cash buyers and over asking price.

Buyers then bought at the edge of their income and when rates adjusted higher the mortgage became more then they could bear.

There'a  broad based economy, lots of qualified buyers, perfect weather, and so many positive things.

I was even so interested in the property I overbid by $5000 to beat out other buyers.
