I have owned a duplex in Sheboygan gateway area since June '19 and can tell you there is a lot of rental demand, especially for moderate and lower priced units.

In no particular order I have listed some of the most popular markets for out of state investorsCincinnati, OhioDayton, OhioToledo, OhioYoungstown, OhioCincinnati, OhioMemphis, TennesseeBirmingham, AlabamaKansas City, MissouriSaint Louis, MissouriIndianapolis, IndianaDetroit, MichiganErie, PennsylvaniaLouisville, KentuckyMilwaukee, WisconsinJackson, MississippiEach of these markets is popular with turnkey investors because of the low barrier to entry, high rental demand & high rent to price ratio.

Lilburn's investment market is strong with relatively low entry prices and strong retail demand.

So if you are buying a home for your family and have a real estate agent showing you homes they almost always demand to see a pre-approval letter. 

Agree with Don and Marcus - I’ve made a living off pricing competitively.It either leads to #1)bidding wars2) lower cost basis#3) increase in money velocity Think of this you price high wait 3-6 months for a deal, end up negotiating down and lowering price increase risk of market changing take another 30-60 days for deal to close another 60 to source and close another orrrrPrice aggressive create demand, bidding wars, buyers into a pipeline make a little less money house sells in 7 days close in 30-60 days another 60 to source and close......Instead of 1 deal with that capital per year you can now do 2-3Increased Money velocity IMO leads to increased annual ROI

This potential tenant sounds demanding, but I can't judge a book by a cover. 

Here are a few thoughts and I would love to hear what others think.Real estate is cyclical and there will be ups and downs caused by interest rate movements, mismatch of supply and demand and general economic conditions related to expansion and recession. 

@Ron Singh the BA is a different animal than most places.

Here are a few articles discussing why this city is on everyone's radar: https://smartasset.com/mortgage/top-boomtowns-in-america-2019 and https://www.fool.com/millionacres/research/top-10-hottest-demand-markets-rental-investment-2020/.

Basic market economics show that we have more demand than supply, which pushed prices up.
