@Robert Gresham google "real estate club homestead, fl" that will be your best bet to find someone local.

Our R&M and turnover are $600/unit (total, not each), and our replacement reserves are at $300/unit.

So this puts the total at ~170K -- however I've seen multiple home sales in 2017 in this area that are in the range of 275 - 350K, and these weren't even brand new.So in other words, it seems like with a couple of months of part-time personal weekend effort, I'd  be able to make a sale profit between 105K and 180K.

Totally missed that it was a mobile home.

Not going to change the world but since I'm not betting the farm I am ok with a little risk. 

If you called them on the phone and they gave you that number, there's nothing wrong with that because they are giving you a rough guideline on what you can figure if you are rehabbing a total basket case, and they have no idea what finishes and timeline you want to work with. 

Conservative investors that pay down mortgages at best garner a 3-4% return on total investment.

You may qualify for the small taxpayer safe harbor depending upon the property basis and your total repairs and improvements on the property.
