Seller finance would be your best option in a market like Florida if you are looking for it to cashflow right away.   

  =)better option is to call a couple lenders directly, tell them you're not ready to have your credit pulled yet, but you want to discuss potential options based on estimates of your credit score, income, etc.you'll get better / richer info this way.  

Real estate is the better option no question.

I charge them a demand fee, like an option. 

The other option is a water tank.   

@Lucas VreekenTypically a reit will pay dividends and has to distribute most of its earnings each year and you will pay taxes on that money earned each year.There are r a lot of passive investing options available

I have been looking into purchase options, but I might consider a lease option because it wouldn't go against my DTI when I purchase another home. 

Any suggestions on which option should i choose?

But looks like an option. 

Especially going the low down option you will get the best bang for your buck.
