Live in it and rent out the other units. 

Does this guarantee that a seller wont give in to greed and try to get out of your agreement? 

I partnered with an experienced STR agent, Troy Nowak, and purchased my first short-term rental in Palm Harbor at the height of the real estate frenzy, navigating fierce competition and ultimately overcoming What made you interested in investing in this type of deal?

Good advice, Do you have any tips for me to build my database more and build my cliental?

If there aren't any massive physical problems with the property, it appears you can grow income and equity.You might be able to buy this with little cash out of pocket if the seller owns it free and clear and was willing to finance nearly all of it.  

You mentioned gross rents of $3400 per month and Principle/Interest/Tax/Insurance of $2500 per month. 

However, some investors don't mind this strategy if they prefer not to put a lot of liquid in up front and plan to refi out within a few years of closing (which seems to be a great option with the talks of the FED reducing interest rates this year).It really comes down to investing in a growing market, in a good neighborhood & building a great team to support you.

I have seen this same house that is vacant (all the classic signs) I have located the owner ( I have not reached out to her yet).

Theres a wealth of information on this platform, and Im eager to dive in.
