I’m considering either buying a duplex or building one, but I’m unsure which option makes more financial sense.

That makes a real difference.Initially we had one originator, one part-time processor, and a part-time admin assistant. 

This will give you one critical piece of information, that it may take X days to get an offer and sell, and the second item will give you what your competition is right now.

Quote from @Stephen Fleming: Quote from @Caleb Brown: I would do one thing at a time.

I have property in three out of four of those counties including one SFH in Madison, one SFH in Limestone on 20 acres that's being developed to a MHP slowly, and one existing small MHP in Morgan County. 

One of them accidentally paid for January rent because of auto pay and is now requesting it back.

I know this is an old thread.I'd like to get a more recent opinion of these apps.I think the DFD options is very interesting.What we want to do is endorse one of these for our Real Estate Club in Greenville, SC and have a contest for our members to see who can find the most deals with the software.Maybe try and get a rep from the company we choose to come and speak at one of our in person meeting and also negotiate a longer trial window if possible for our members.

Some commuters to Dallas, because rent is cheaper in Sherman than Dallas.As far as DFW metroplex goes, probably one of my favorite cities for investment right now.My thought is look at newer homes vs the 100 year old ones. 

Unless you have unusual circumstances such as a month of DIY repairs on one of the houses, your wife would need to find more real estate work for herself. 

one infill house I did in Charleston we made 600k net on that one in 13 months.. so not bad.
