However, since the average lifespan of a U.S. company ranges from 10 to 18 years, most private-sector jobs your tenants hold are likely to end within that timeframe.

During the due diligence time frame a lot of my conversations with the owner were had over the phone rather than in writing, via email and text. 

Not sure on your timeframe, but AZ is currently a buyers market (like I'm sure a most states are) due to a rise in inventory and interesest rates.

First, not all lenders require a seasoning period and when a seasoning period is a requirement the timeframe varies lender to lender.

And if we don't have an actual buyer in that timeframe, does the EM have to come out of our pocket?

That time frame will determine your RE strategy. 

And it runs 1 asset at time with flat costs/time frame and we know each state is different.  

This way you can easily refinance in a short time frame after closing and capture the equity you are obtaining from getting a property at such a quality price. 

That's if you wanted to buy land and build them within that timeframe you are permitted to as long as you can close within 180 days. these are 3 story walk up triplexes urban infill with tax abatements. we have 8 approved so far. you could also look at land plays to grow. i don't know how much you are receiving from proceeds but I could do a few financial models to show you.

However, I do think the conversion time frame of 60 - 120 days still stands, regardless of how motivated your list is.I would ask if your agency can text for you.
