I would love to have some clarity and steering in the right direction as to the best source for FHA loan information and caveats, as well as any tips for a 22-year-old single investor planning on house hacking for my first real estate investment.

One more tip – people remember stories that trigger their emotions.

It's a tip I heard from someone which I heard increases the response rate. 

That's not exactly an up and coming area -- I'd research who built them - can likely find that by going to the SG County Recorded Docs site or by seeing who pulled the permits during const -- Wichita has been on a duplex building boom -- look at the tax value -- They probably have that or less in it on the build - I also doubt they were built to be quality long term -- things such as the trim/cabinets etc -- they all look like the cheapest stuff a guy could buy - if the cabinets aren't oak and there is MDF or pine trim and pre-hung doors with engineered wood jams I'd run.  2-3 yrs ago for $180k -205 or so you could buy duplexes in Maize, Kechi, Valley center all day to builders that were selling them off to investors - not worth that in that area.

I have an outdoor pool that easily have 1k+ people using it every season and I never had single complaint due to the water quality.

Not the case.Just like everything else, there are always different quality of Section 8 tenants.  

Other introverts will feel comfortable with you and that could actually help your journey......more important qualities are honesty, integrity and being a harder worker than others.Just be yourself and go get started.

Just trying to gather as much information and tips as i can
