Plus new construction will be to today's design trends, so you should rent quickly and be on the high end of market rent.

The way I have attracted most of these lenders has been through posting on BiggerPockets and through my meetups.

Any particulars that attract you to Columbus?

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. 

It needs a kitchen, a couple of windows added and permanently closing the garage door.What software programs do you recommend to put together designs for these ADU's that I could take to the county planning commission.

The building was not designed for cash flow so you have much higher expense ratios and more headaches to contend with.

These loans are designed to stimulate homeownership (not investments).
