@Brian Stike  You can cash out 70% max if purchase  this property  less than 6 month before under conventional loan. 

If they charged a bunch of fees upfront and promise you the world, scam.

It may sound nice to pay a 5% management fee but the extra fees can add up to be more than the other company that charges 10% with no add-on fees.

@Ray Rhoads job history is going to be an issue if you are applying for a conventional loan. 

Well technically if there is no paperwork then they're not tenants and you should be able to evict them or charge them with trespassing

Due to the fact a lien can be placed on your home if the bills are not paid, I would recommend back charging your tenants for the utilities.

Is 0.75 multiply against what is charged for rent for the month or is multiply to the cash flow I get after I subtract all expenses such as insurance, taxes, and paying the existing home mortgage?

Those two platforms have no booking fee and charge an annual subscription rate to advertise your STR.

I think 800/mo is reasonable rent expectation, that's what I charge for the 1br unit in the duplex I bought, and other 1br units are renting for 850-875 in St.

I then charged the upstairs tenant $25/m to access the internet & relisted it at $1000/month.
