Also, what happens if the loan is due while a property is under contract pending?

Cash flow maintenance cow pending on age.. 

yes, get some confidence in those numbers first (including your ARV value). these numbers do seem to work, even at 160k, pending your exit value is correct at 500k. i'd consult with some local heavyweights like @Will Barnard that have experience with expensive/extensive builds, tho. 

Once it's pending and has been set and docketed at the courthouse, the homeowner can accept an offer, but it would still need to be approved by the bank if there have been lis pendens filed.

If the Tennant's are home I will be nosey and speak to them about their experience and if there are any pending issues that need to be fixed. what list of things should I be asking for from the current landlord? 

The property has been in 'pending' status for 2 weeks.The second is less attractive, but still not bad.

I can provide specific numbers and figures if anyone is interested, but a quick breakdown of figures pending the rental income I believe is a good price (lower than a rental analysis I had done on the property) - we would come out essentially even annually or maybe barely in the red (if we are conservative with savings for improvements, maintenance, emergencies etc). 

My offer (accepted, pending, waiting foundation report) in all cash, but I realized that mortgage rate is pretty low lately, and I should put 50% down and finance the other 50%.

Anytime we get a call about anything, we respond in less than an hour or so, and try to have it resolved in less than 48 hours if possible, pending availability of the plumber, contractors, etc.

This should also set us up for success with hitting our goal of 10 units by the end of 2022 (we currently have 2, pending on that 3rd).
