As to the original question where to get the data  I highly recommend Property Radar  check it out.

She does not have money for her expenses and is borrowing at a high rate of interest which is becoming impossible the idea is to sell my cousins rental property take a boot to cover her expenses and the rest ($750,000) do a 1031x.  

If you are carrying a high note and this is indeed your only investment I do not think there is an issue keeping this in your name. 

Most don't allow any under 31 days or so and some as high as 6 months.I would say adding another bedroom would be better for the long term rental rate + appreciation.

Also, consulting with an attorney specializing in real estate and business law is highly recommended for this. 

Due to the high real estate costs in my area, I would love to connect with investors who have had success investing in long distance real estate or have completed a house hack in the tri-state area.

Is it really that good given the high premium and lack of ability to change many options?  

A lawyer that I know highly recommends him for SDIRA CPA stuff.

Refi hustle might be real, but it's doable with the right prep.I have found a good property (for rental income) but obviously the inflated price with high rates makes it an OK deal instead of a great one.

In markets with post-occupancy or quality-control issues, the inspection process became absurd.
