@Bernie HuckesteinIt depends on the fees you are speaking of.If you are talking about administration/transaction fees from the custodian, such as a wire fee or annual record keeping fee, you can pay for those with your personal funds.If you are talking about fees associated with the actual investment, such as landscaping or a contractor the IRA must pay those. 

Let’s assume I am looking into properties that have rents that can sustain Insurance, Property Tax, CapEx, Vacancy, Repairs, Water/Sewer/Garbage, Landscaping, Management/HOA fees and mortgage, AND still cash flows.

New floors, removed popcorn ceiling, new paint inside/out, new tile/carpet, new light fixtures, landscaping front/back, granite slab in kitchen, new appliances.This was a 2bd/2ba that rented for what many 3/2s go for in the market.I read somewhere on BP that a quality rehab draws better tenants, as I am only two months into the lease, I cannot say for sure, but I am hopeful.

That's also not including management, snow/landscaping costs, or any other unexpected costs. 

Outside of that, paint and Landscaping can go a long way to beautify exterior on the cost effective.

Any advice on the Puerto Rico Real Estate landscape would be much appreciated.

For example, consider logging that could change the landscape drastically, or surrounding area rezoned from residential to light industrial or other use. 

Just my perspective here :)  I think it may help to adjust your expectations a little - hear me out ---  while you may find what you're looking for, I think it will be harder to come by because of recent policy changes and the big picture of the policy landscape currently..There are cash flow properties, and there are equity properties. 

Holding costs are usually: property taxes, insurance, utilities, HOA, landscaping, financing costs. 

This includes; roof, HVAC, plumbing, all surfaces, some wall removals, landscape, mold/asbestos remediation, foundation issues, sea wall repair/replacement, etc. 2021 +Once I move to SE FL, I do want to buy two/year 3/2/2 SHF homes and rehab these.
