I had a few tenants e-sign 6 documents with multiple pages in a couple minutes and realized they did not read any of it! 

What was your experience like?

Main questions should ask about the seller's:- Reasons/Motivations for wanting to sell- Desired timeline to close- Plan's after selling (relocation, reinvesting proceeds, 1031 exchange, etc)- Back-up plan in case they are unable to sell within the desired timeline- Reasons for not already selling to/with a investor or RealtorAdditional questions will depend on the type of seller lead i.e. pre-foreclosure, probate, fsbo, absentee owner, etc.Here is an example of a youtube search you can use to begin finding call recordings.There are 1,000s and you'll find that the best/most effective ones don't even sound like sales calls.

It depends on what you are trying to do.

If they decide to move out you can do the remodel. 3) are the tenants in any kind of financial situation to buy the property?

@Jim G.Per the International Residential Code if the glazing is less then 60 inches vertically from a standing or walking surface then yes it’s required to be safety glass as it’s considered a hazardous area.  

TrueDoor appears to have a great reputation online, I'll be giving them a call.

Did you pursue it and close any deals?

What made you interested in investing in this type of deal?

Did you check a next door comp that just went into contract?
