Mid-term is more likely to work in any market than STR, but I think you would be surprised at how well an STR could do if there are no other options like that in the area (think people's parents or friends coming in for the week(end)).I've seen a lot of people grimacing at the net-negative house hack (it's just a product of rates and low inventory in a lot of markets) and this is one option to try to recoup some of that loss.

Also, the monthly cash flow always negative, why is that?

I was going to checkout Truebooks and will not because of only negative feedback from you. 

Also, focus on 2 years of job/income stability.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560 (almost 30% probability of default), little to no good tradelines, lots of collections & chargeoffs, recent evictions.

A quick fix now can save you from potential negative feedback later on.I'd be happy to discuss more ideas!

I also found that being at "market" rents it takes longer to rent therefore missing out on a month or two of income negating the ROI on improvements.

And if CA and such has negative cash flow but good appreciation.. then maybe I can find a place that has a balance of both. 

On the negative side no one wishes to rent long term here!

And considering I think a person who puts in plain black and white that integrity and character of the operator are key -- and then does something underhanded and incompetent is just mind-boggling to consider -- so I'm only left with a negative feeling about the documents these darned attorneys dream up!
