If the ADU actually costs you $500K, it's barely worth it in terms of cashflow.

I was barely covering expenses and many months lost $100-$200.

They simply manage the bare minimum requirements of the transaction.

Since you are just graduating college you may already realize that it's not what you know, but who you know (as a personal note, I had college friends that were barely passing their classes however they ended up with really good paying jobs due to "who they knew").

Its a strategy that barely even worked few years ago but currently airbnb rents are DOWN across the board and LTR rents are UP, the trend changed last year due to so much airbnb supply it dropped the rates and airbnb also got stricter with cancellation fees as well as giving guest refunds more often. 

We are barely getting $2,500 for SFH homes with pools in nice areas of Cape Coral.

If they can barely pay 3 or 3 1/2% as a down payment for a home, how are they going to pay to have representation?

I paid the obnoxious neighbor back by running my fence all the way to the street and cutting our conjoined driveways in two, leaving him with barely any room to open his car door, since he had been parking on my property the whole time he was harassing our tenants.The lesson is of course to just get a survey done. 

Since you are just graduating college you may already realize that it's not what you know, but who you know (as a personal note, I had college friends that were barely passing their classes however they ended up with really good paying jobs due to "who they knew").

I'd rather have a few really great cash flowing properties than a dozen that barely cashflow.
