I currently live in gwinnett, GA in a single family 4 bed 2 bath house. 1400sqft.  

Both units are 2 bed 1 bath at 860sqft that includes a garage space each.

Semi locally, in a worse location, I know of someone that has built around ten 2 bed 1 bath homes that were rented before they finished the build and have been since.

@Jingwen Dunford I hear you, I'd like to outsource landscaping for my rentals too but I have yet to find a cost effective option so I mow, trim and spray myself and keep the plants and flowers beds to a minimum lol.

It started out as a 3 Bed 1 Full bath and ended up a 3 Bed 2 full bath.

What’s most important is picking comps that are similar (e.g. same beds/baths, sqft, renovations, recently sold, etc.).

First thing would be to find two bed rental comps in the target (sub) market. 

Louisiana Mobile Home ParkPurchase Price around 230,0005 units-3 bed/2 bath homes all park owned monthly rents of $4,000decently kept up and renovated units with long term tenantsThe numbers seem to be great compared to a fourplex.

Coffee and comfortable beds are most important in my experience!

If you're tired at 9 PM, go to bed.
