Curious to get some tips from folks that have a larger portfolio (say 50+ units or larger) across multiple MF buildings (so different acquisition dates, financing, etc.) and what software you use?

Then telling folks you're a rookie?

I've been helping folks navigate this market for the past 20 years, and I can tell you, combining a personal residence with rental income is a game changer.Just last year, my friend Dom helped a new investor find a charming duplex in East Austin.

Wanted to start a thread and hopefully gain some insight into folks who have purchased automotive dealership lot/store fronts and leased them out? 

There are a few folks in this forum that may be willing to lead the way.

You have your screening criteria for a reason.If it works, and this person meets your criteria, move forward.If they don't meet the criteria, on to the next.A few folks here have already touched on this: keep in mind the implications behind early termination of the lease and how to reimburse money if it's required.

And since the loans were not in their names and as you note Sellers did not know to ask for PG ( although in these cases PG is worthless) These folks walked and left the sellers in a very bad way..

This will help you plug into the community and see when folks are talking about your local market. 

I would first start by talking to folks in the Temple area first.

Keep practicing, ask lots of questions, and don't be afraid to reach out to folks who've been down that road.Looking forward to seeing how your journey unfolds!
