Since all of this money is being borrowed and paid back in a short amount of time.

  $28,000 for one full year.  

It does come down to your goals, your time to allocate, your business sense, your ability to bring or raise capital, and what you are trying to accomplish.I am personally not a fan of short term rentals, as it appears regulations in many cities keep making it harder.

It's definitely gotten really popular over the past few years and some people have built very successful businesses off of it, but if you aren't looking to do that full time then I would recommend buying a property instead as your margins will be far better and you have more options to get out of it if the market or your rentals go south.

You can usually also benefit more by simply using the seller or builder credit to do a simple "Rate buydown".The first rate on the buydown is a "teaser" rate that only last for a short time 1 year for example but a true rate buy down is for the entire term. 

I am a first time investor and am currently under contract for my first property (yay?!).

Are you offering full price to start off with? 

Any advice for first time buyer on where to find private money and/or a good realtor/property managers in my area of purchase.  

While everyone has to start somewhere, too many first time investors will waste your time, when you think they are serious, and never buy a property. 

In past judge always side with tenants on section8 no matter what.So plan is- non renewal notice 60 days- send eviction 30 days notice at same time so we can file eviction if she does not move out on 60th day- put renters insurance violation as reason rather than non payment of deposit as judges can always show sympathy for monetary issues?
