I think you should change PMs because you have multiple complaints.  

I offered to show multiple people the numbers on my current RE holdings and to discuss what had been done. 

From a lender’s perspective, hard money and private money are exactly the same. 

Customer service from a support perspective matters of course, but no hang up or delays on investing would take place.

For example, should we focus on acquiring one high-quality property in a strong market, or would it make more sense to spread the investment across multiple lower-cost units in emerging areas?

WARNING: if you do not prepare for this, you can enter a death spiral: deteriorating properties lead to lower rents, worse tenants, more wear and tear, even less cash flow to fund repairs and ultimately erode asset value.I do not mean to rain on your parade, hopefully, this is a helpful long term perspective. 

Great feedback, if you don't mind me asking you, how are you finding multiple handymen/foundation repair salespeople to network with?

I would not renew the lease based on multiple violations you noted, but also because you are jeopardizing your good tenants' ability to enjoy their living spaces.

My lender at the time ASSURED me that it was totally fine, as I had asked him explicitly multiple times about refinancing a year or so later and he knew about the lease.

If your business operates in multiple states, you may still have tax nexus and filing obligations in both, regardless of your LLC’s location.
