I have the impression that portfolio lenders give loans based on the performance of the properties.

But as a personal investor myself I would say look for someone who has done volume, compare their rent estimate on rentometer, look at comps to compare their price, check them out on Better Business Bureau, ripoffreport.com, turnkey-reviews.com, things like that, ideally tour the places you are considering, but that might be a stretch from Hawaii  

If the rents support the mortgage and the note has a good performance record then the lenders will be more inclined to work with you.

On Parris Island everyone yells at you, but it was the first place I had ever been where people treated me according to how I performed.

Action is great but just ensure you are performing your due diligence.

Your best option is to get the full property performing before you move in, as your occupation in the larger building does not enhance your cash flow. 

If you do most of the work I can see you stretching your 500 if you out source its going to eat it up.
