Buildium was honestly difficult to get along with for a while.

Any ideas of what to do This is a difficult question to answer with no numbers.

Looking for some opinions on how to proceed with some difficult mid term tenants.

Good places are Arlington and Fort Worth in my view.Townhouses and condos are difficult beasts, I would prefer townhouses, I have some investors friends that they didn't want to go with a mantainance headache so they bought townhouses, but those are expensive and they are Long-term.Condos are a bit old in DFWHowever, all deals on that you would need to have an investor friendly realtor to help you with.

I have a high credit score, good income, and money in the bank, but I have been having a difficult time finding a DSCR lender I feel like I can trust.

(other than having cash/equivalent, preliminary title report, and the appropriate deed ready to go 'on hand')The MOST difficult part of this will be getting the lender to provide you with the reinstatement figure to bring the loan current (I do this and take title sub-to because it's actually easier to get the lender to provide a reinstatement than a full payoff). 

It's too difficult to narrow down a KPI that would attract someone.

The higher rates have somewhat slowed down the "get rich quick with no money down" crowd as financing is more difficult, but I still see a lot of new investors with serious cash or purchasing power.

And of course those are highly difficult locations in CA for development and building permits..

Difficult likely to get rid of bad tenants and paperwork night mare.
