It's more of an issue if they keep missing payments and eventually have to be evicted...but that can happen any time, regardless of a crash.The only major dangers I see are: a substantial decrease in rents and now your expenses are no longer covered (generally not a huge risk) or if you have an adjustable-rate mortgage (hopefully not).

Point is, if I don’t sell in the next year or so, I have major capex coming (10K roof, 10K furnace, 10K plumbing pipes, 5-10K exterior paint).

Would I have better luck with pricing if I go to a lowes in a major town?

Unfortunately the office staff hadn't been very diligent about requiring proof of renter's insurance from our residents this year so we ended up having to cover a majority of the costs.

Literally ate Ramen Noodles twice a day majority of a year to save money to invest.

Do that and you will not have any problems.Don't ever miss a payment again.If you can not pay all of September on time I suggest you pack your bags.My guess is your landlord does not know how to evict legally (majority do not) and will likely not be successful.

The city this building is in expects major economic growth in the next decade due to a major factory opening, which should drive up appreciation and rents as well. 

But again, we're not talking about a complex in Denver, Chicago, or any other major market that has significantly higher rents.

Is your major business related?

I think right now there is just this major thirst for doors doors and more doors.
