We’ll only lend after we’ve met and gotten to know you just a little, you must be a full-time house flipper, and you must have a good deal; for which we provide specific criteria.Obviously, this only works locally, and it would be impractical if we had to deploy many tens of millions out of a fund.

Just ensure that your increases comply with local rental laws and regulations. 

I just let Airbnb do their thing and do my normal due diligence on Airbnb guests like asking why they're coming, making sure they have a valid ID and try to avoid locals unless they have a good reason like home shopping

Yes this strategy works great especially if the numbers don't work locally.

To get a good rental income, be sure to check who you rent to very well, write a clear rental contract, take a security deposit, make a smooth way to get rent, keep the house in good shape, think about getting landlord insurance, keep talking to your renters, and follow local rules strictly.

I manage & do all of the setups because I'm local. 

Do a thorough market research and consult with local real estate professionals.Good luck!

@Keenan Branch this is a great question but I would suggest treating this like any vendor for your market. 

Your answer would be it depends on a million things.Like the specific property, its condition, location to desirable areas, local STR regulations etc.We would need much more detail to be able to help.

My hope is to begin building my portfolio (probably fix/flips) this year while I continue to work with local investors on helping them build theirs.
