Solution:  Only hire contractors certified and registered under the RRP rules and do the best you can to make sure they are following the correct work practices, documentation and clearance tests. 

I'm not sure I could sustain an LLC without asking for more money for every new property.  

keep in mind they were aiming for 5% and it still nearly eliminates the incentive for the only solution, new supply and maintaining the existing supply through value add programs. 

If I can just show ONE person that has made it sustainable, it would be enough to end this discussion.. in your defeat!

And further in my mind 50k type properties should be paid for in cash .. that's really the only way to get sustainable REAL cash flow that could be spendable.But I personally agree 100% with your advice 

To be honest, the local economy can't sustain these higher prices.

I try to check out possibles and may drive by where they live and see if they really do and have talked to neighbors I have had owners tell me "don't to rent to them,"I will ask relatives or friends when I can if they would rent to themWhen Granny warns you off or an uncle says "you don't have to worry about money with them two and pauses and said you won't get any years back I didn't worry much ,had a few people who would find creative solutions to problem tenants if I was silly enough to get suckered in

Is there an all-in-one solution?

My guess is that behind such specialties as a solution to every thing that comes along, you'll find someone who lacks knowledge, manipulates others to facilitate a transaction, someone who will be defensive about what they do as an ethical stance, that attempts to use loopholes or convoluted strategies as a marketing aspect convincing others that they can avoid matters that may restrain business.

Looks like you found the ideal solution.
