To me being an agent for all these decades .. its a lifestyle choice .. its not a job per se. mainly the more successful you become as an agent the busier you get.. there are so many perks to being a successful high producing agent FAR in excess of just the commission income. 

Like a 600SF AirBnB rental in its place just to qualify for a traditional mortgage.

@Yashar Fred most traditional rental investors that I know here in San Antonio are getting just over neutral cash flow in year one, when choosing areas where they expect strong rent growth and appreciation.

I would appreciate any experienced real estate investor who can help me make a good choice.

or is there other options that would be a better choice?

Hopefully you don’t have a problem around the entire house, which I have had before, and my only regret was not peeling it away all at once to manage.I’m happy to help talk through this stuff with you if you need to speak with somebody on the phone that can at least help you think through your choices.

short term rentals are not only vacation homes, nurses, workers, consultants, family, etc. all use short term rentals in traditionally non vacation markets

Their parameters for qualification are totally different from traditional property investment loans.

Lastly, are there resources about FHA vs traditional mortgages in terms of expected returns?

Here's what we do (copied from our website):Screening ApplicantsPoor screening often results in lost rents, legal & court costs and costly damages.Screening of applicants includes the following:Full credit/eviction/criminal checks are done, instead of score-driven reportsVerification of rental history includes validation of actual property owner to avoid fraudVerification of stability of income & employment via YTD paystubs & W-2(s) (analyzed to confirm not fakes)Income is calculated 3 ways to spot stability anomalies: pay period, YTD average and YTD + W-2 average.Debt-to-income analysis (more accurate than traditional 3x rent requirement)Bank statement to see if NSF issues, if deposits support income, prove MoveIn Funds, also analyzed for unusual transactions.Pet screeningHolding Fee required from approved applicants to make sure they are serious, before your property is marked pending.
