I found it odd, too. 

It can be true, but remember lower price just attracts customers who are cheaper and odds are good you end up in a lower margin business. 

Odds are good the lot was surveyed before you built on it and may even have metal post markers still visible.

Given the Atlanta area and what others already touched on, there are a few things you can do to put the odds a little bit more in your favor so that once you find a deal you can move on it much more quickly. 

My goal is to buy and hold out of all deals (except for the odd one). 

@Jason Tefft Yes Ankeny is a great area, but the flip or BRRR deals I've seen there are 190-250K and purchased with cash so you have to have both the financing and be willing to pay a bit higher price point than other parts of the metro.Obviously, Ankeny is growing like crazy, but I'm just not sure the BRRRR or flipping model is best suited for Ankeny, you might find more success in Des Moines Proper areas unless you have a reason to buy in Ankeny, those deals will be VERY tight and very far and few between.Also regarding wholesalers, agree 100% I haven't seen a "good deal" from a wholesaler email in over 18 months and I'm the odd real estate agent that subscribes to ALL the wholesaler email lists :)

Oddly, several agents I spoke with were not interested in listing/renting the unit. 

I will probably read on it a bit more, but odds are that I will let the idea burn out.

Odds are good they will want another dog (even though they may say no now) and puppies are much more likely to do damage.

Your odds of purchasing a SF are a lot higher and they can hit your financial goals as well.
