The Bigger pockets book, finding and funding great deals 2017,  is a great resource.

I'm targeting small multi-family deals from $500k to $1Mil with long term financing in place.  

It is a great resource for education and networking.There are any number of agents from the Cleveland area who are regular contributors to BP. 

You need to take into account your long term goals, your short term goals, your resources especially finances, and your risk tolerance. 

As a homeowner already, you have demonstrated that you have the capability and means to purchase a home, so you aren't the target for this product.

If you know why they don't want to lend you in the first place, then someone here might be able to point out to the best resource.

As you mentioned, there are several new construction developments close to Disney that target the vacation rental market.

Following is a good resource on the rules. https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-topics-prohibited-transactionsAnother option is to open a solo 401k if you are self-employed and then you can borrow $50,000 once you transfer the IRA to the solo 401k plan.

The compliance costs are more than just paying professional managers and may mean more larger, institutionalized ownership (with resources for a law firm to constantly fight and full time professional managers able to keep up with all the rules)... 

@Andres Gonzalez Welcome to BP, lots of great resources on the website + there is a local meet up as well that's great to connect with local investors.
