I am pretty confident I can fill the vacancy immediately, and probably charge a higher rent as well.

Commercial property can take a considerably longer to fill a vacancy.  

I'm in a trendier up and coming area so the upper unit fills quickly and I've seen my property value jump quite a bit in the last 2 years.

Social media is filled with 'passive income real estate' but it takes a lot of work to acquire, qualify for loans, and manage property. 

How does one go about making an offer on a commercial space that is becoming vacant shortly, such that if I cannot find a qualified tenant to fill the vacancy that I can walk away from the deal? 

That would NOT be enough for me to buy 100 units unless it's a incredibly low price, then work on filling the site with long term RV tenants while I wait for the new reactor and cashflow in the meantime.

I virtually always fill the unit at the 1st open house.note if you find it hard to rent in September, imagine the difficulty in Nov, Dec, Jan, Feb.  

Usually in this limited case having the ongoing litigation or even a judgment can lead to disruption in their business (ever fill out a PFS and have to check the box actively involved in litigation?)

One application, one credit pull usually, lots of lender options....vs filling stuff out over and over.

She started dating this guy, moved him in and when we demanded he fill out our our application or move out.
