When you’re ready to retire and want cash flow downsize and move funds to a go NNN net commercial property. 

I'm biased and can provide reasons and data to show that using an agent will protect you, get you more money, less stress and so on.The reality is you can do it yourself, but tenants generally don't cooperate with showings and that causes lots of problems for buyer to access the unit to show, inspections, appraisals etc.

I would suggest you talk to a mortgage broker or a bank though - if those homes are zoned commercial you will probably have a hard time getting an FHA or low down Conventional mortgage.

The property has about a quarter mile of street access, and no trees or anything to block it, so I wanted to put something there to give a little privacy anyway, and then these trees obviously have to go, so I was hoping to re-use them.

Unless you are dealing with commercial, TREC 1-4 works perfectly well. 

Just make sure only YOU have access to thermostat.5) First understand that leasing is a DIFFICULT job!

Commercial properties owned in an HOA tend to have issues with financing.

Navigating NYC's zoning regulations can be complex @Jon Pflueger, especially in M1-2 districts, which are primarily designated for light manufacturing and commercial uses.

You get the best of everything- cheap, tax free access to your equity, you get to keep your interest rate and you get the cash flow.
