I tailored their lease form for the tennant I accepted, and used their template for each tennant I rejected.

In fact, if you accept responsibility for some accident or screw up, your insurance company might walk away!

The second of those seven offers was accepted at $23,900 for a 2/1 house in a subdivision with recent comp sales around $65k.

Before you do any of that you need to decide what the comps are in the area of recently sold homes similar to that one.If the house needs nothing I highly doubt he would accept 120k for it unless it needed a lot of major repairs.. 

Not the case with an auction however, which will require you to close as-is, where-is, and accept the good with the bad.

I think he'd accept $30,000.  

Do you make them a verbal offer and then if they accept do you send them (email/mail/Esign) the purchase agreement?

Some of these may not show up in a title search and could come back to haunt the lender if he voluntarily accepts the property.

You should find out from your local building department if they will accept what is known as standard construction plans or if you will be required to have them produced by a licensed architect and licensed structural engineer.Usually if your city will approve your proposal the electrical and gas meters will be installed , after your inspections have been approved.

The home failed the city's sewer dye test after my bid was accepted but before my home inspection.
