Perhaps a nice 1950's built bungalow.Always hire a 3rd party property inspector to give you an unbiased feel for the home.

The whole point of Real Estate Commissions requiring licensure is that the wholesaler is actually operating as a real estate broker, and hence as either an agent of one of the parties or an intermediary for both.  

Also, there was mold and so we got bids to have it fixed, they got bids that were WAY lower than ours,  our mold guy told us to have a third party verify the work and so our contract says that he would test before and after and approve the work.

Conservative and aggressive methods please

I'd say it also depends on how conservative your numbers are.

Be confident in your numbers and make estimates on the conservative side.  

Some realtors would tell you otherwise but from my 3 years evictions experience, rules/laws are stuck to the lease/contract and not to a new party entering the contract.

The expiration date of an offer can easily be crossed out and extended with the acceptance of both parties. 

They might have a 20 year amortization at a slightly higher interest rate from a local bank that wants to be conservative and get more cherry terms on their side.

Honestly, though the third-party services like Zillow, ect... have it down pretty well. 2.)
