Dealing with the fallout is always worse.I have no idea about this situation as I wasn't there so not advising you to accept or not accept. 

Key things to look for:(1) Experience - however much you deem acceptable(2) References - contact the last 3 customers they did similar work for(3) Compliance - be sure they're following local rules in regards to permitting/inspections (4) Specialty - a lot of guys say they do it all.

Paper currency got its start as little promissory notes to pay gold, and then because the notes were more portable than gold, people started using the notes as money instead of the gold itself, which is why you sometimes see references to "one dollar notes", etc.A seller may or may not accept a promissory note as payment. 

It's a process that includes both the research of risk in a transaction, and finalizing the acceptance of that risk. 

Part of that system is a set of criteria for accepting a tenant.

My offer just got accepted on an investment property.

I am too busy with my current clients to accept a new investor client. 

* Yes you can, but again, some sellers do not like FHA loans, so having your offer accepted may be a little harder

As long as the prospective buyer accepts the deficiencies identified in the inspection, and the sales price is in line with the appraisal (or the buyer is willing to pay the difference), there should not be any issues here.
