How Can Private Lenders Ensure Flexibility While Protecting Their Interests?

Of course, this is just my opinion but I bet I'm not alone..If I'm an investor, I think the returns you're able to achieve in Costa Rica are higher than normal because you focus on these large properties and, as @Martin D. mentioned, prices in that country are too high and returns too low.

I am wrapping up my licensing education with the intent of being able to buy and wholesale solo part-time, while keeping my full time job.How would I go about finding a brokerage that would sponsor me as a sales agent while allowing me to have this flexibility?

If I were a betting man, I'd say there is a good change that the Midwest will outperform FL next year.

I'd also go in with your own agent.I'd bet the listing agent's company is keeping the deposit even though it is meant to be in trust. 

@Dan DeGroffTo achieve a house-hacking dream in Washington, consider lender flexibility, documenting intent and income stability, applying for an investment property loan, partnering with a Washington State resident, exploring creative financing options, and considering FHA or VA loans.

It has been my experience, too, that smaller banks with a deposit relationship have a lot of flexibility and a variety of products on offer.

Most importantly having the 5 separate  tax ID’s will give you the flexibility to sell the units individually in the future or perhaps it becomes a potential exit strategy you pass along to the next buyer.

If I was a betting man I would say the answer to that question is NO and they are likely promoting the 2-3% success stories as the norm and therein lies the problem.
