I have a 3 bed single family in Atlanta.

The room is also furnished with a bed and drawers.

I think it's a hard question for others to answer for you, because it's entirely dependent on the nature of the project and your own interests and aptitude.I was my own GC (while working a full-time W2 job) on a 6-month remodel of a big house where we reconfigured the interior space, including relocating a staircase, converting part of the garage into an additional bed + bath and replacing the kitchen. 

Both of the units are 2 bed/1 bath.

I've done some rehabs to make it livable, but I'm finding it a bit challenging to rent out as a 6 bed, 2.5 bath house, whether as a whole or by renting out individual rooms.

We purchased it in November 2020 right before the pandemic at a purchase price of $330,000, a 3 bed 2 bath with a detached garage that was converted into a small room.

Is he a GC and they fall out of his truck bed, is he doing work projects in the dwy, there must be something specific...So first thing is if the other tenant is causing this, then they should be paying for any repairs and tire replacements.

They can look up the sales for last 6 months in any area and then from those sales pick out the houses with similar square footage, same bed/bath count, and then average those sales out and that's your ARV.Florida can be rough. 

Two Bedrooms with King Beds and one bedroom with 2 Full size beds.

Thank you for this info. my current home is 3 bed 1.5 bath and just under 1100 square feet.
