They told me they have a few SB-9 applications in process and expect it to take 3-4 months (ADUs they're deciding within 30 days).

The return on equity is probably very low considering they are paid off so maybe explore refinancing or selling the lowest performing one(s) or your biggest headaches to reinvest in more lucrative deals.I noticed you also used a metric of number of rentals to attain your goal rather than $$$/month.

The property management company I use charges you for pictures.

It really seems like the forums have been off for the last few months I've been reading them. 

It’s a lot of work for a measly 200 dollars a month which is the typical cf on a 60-80k home that rents for 850.

They're opening up some investment opportunities for 24 months.

In my devious mind, I thinking like you that I hire a parking attendant, install gates and charge an entrance fee if I bought it. 

Whey are you looking into a HELOC a month before closing on your first property? 

Depending on the application, first, last, security, and another month or two.

Now that the unit is finished, it's going to be listed for $2,450/month and the same model on similar lots are appraising for $410k.
