I think the rub you are feeling is based on the fact that fewer homes will produce a positive ConC than you might think. 

Key criteria for a successful SFH househack:Suitable zoning criteria, i.e. room rental laws (county by county)Within 1 mile of hospital, major company HQ, public university, and private university (to attract 20-somethings)At least half as many bathrooms as bedrooms (i.e. a 4 bed / 2.5 bath could work, but 4 / 1.5 could get sticky)Plenty of driveway space / street parking (1 per roommate)Plenty of kitchen space (since the kitchen is the most occupied room other than individual rooms)Basement or side entrance entry point (i.e. if you wanted to turn the basement into your living space, you could enter from a side entrance)Un-involved neighborhood community (cul-de-sacs can be the worst spots)Turn-key quality (i.e. you won't need to fix much of anything when you move in)This list is by no means exhaustive, but things to think about when you work with an agent on a SFH househack.

President Biden is calling on Congress to enact an innovative, new competitive grant program that awards flexible and attractive funding to jurisdictions that take concrete steps to eliminate such needless barriers to producing affordable housing.See my post on Raleigh zoning changes to relieve 2/3/4-plex shortage regarding one city that anticipates federal funding grants for this purpose. 

Ideally I would like my property to attract younger tenants (under the age of 35).

Agree with @Jarrod Covey - Bastrop is attractive with Tesla coming. 

Why an investor want to sell a property that producing 20% cap?

We are working on locking up our deal tomorrow hopefully, figured it would be wise to figure out the best way to attract contractors w/ good skills but understanding that this isn't a one off and is rather a relationship building situation.

@Lawrence ChenThe first step I’d do is write down your goals and expectations for an investment - what cash flow do you want, how much time do you want to spend, what condition of home, what about a market attracts you, etc.Then once you have a better idea that, I’d recommend to start reaching out to agents who are also investors so you can learn how the local markets are operating and how the on-market MLS compares to off-market deals.Overall, the Midwest is great.

If your numbers still work, pools can be an attractive feature and could fetch higher rents.

with a $100k investment, the turnkey, (80% ARV LTV) produces a 40.8% return.
