Every time my property manager knocks on the door no one answers or they have there kids do it and say there parents aren’t home.

I'd think a clean well taken care of place to live for $500-700 or whatever your rent range would be...would be no problem to find a good tenant - We lived the life of renters for a year and a half or so for the first time in our lives and quality rentals that are reasonable in Topeka is akin to winning a lottery ticket -- if you can't tell I was quite discouraged and very disappointed most of what's available if it was nice went immediately for ridiculous prices and most of the rentals were garbage for what was charged.My perspective comes as a home owner the instant I moved out of my parents house at 24 and then starting to own rentals at 26 and having never rented - so I'm probably again suffering from bias and a jaded perspective having been forced to rent. 

Have parents co-sign.

I know if you buy a house for your parents you can still take out a conventional loan but am not sure about buying a house for a sibling to live in. 

I don't feel like I own this tenant anything, as they have been bad neighbors above all else, but I am troubled by the idea of putting a single parent (who is out of work) in this situation. 

I'm gonna try to make this short, but bear with me, it has alot of moving parts.My sister met this guy, became pregnant, we lived about 45 min away from where the BF lived, the BFs parents wanted us to move closer to them, so everyone could be with the baby, the Mom of the BF had a 3/2 and said we could all move up there, myself,my mom,my sister and my sister's 5 year old son.

I would hope the parents can control their kids.

Withholding info is not supportive of that goal.* With COVID has your buying strategy shifted?

My wife and I, not only donating thousands of dollars and hundreds of hours, received PTA "Parents of the Year" awards, my small business was a partner (funding "regular" lunches for students without funds) with the LB Education Foundation, and I was a volunteer athletic assistant coach at Poly High School.My recent records request shows that in the 18 months subsequent to implementation of SB 13 (Jan 1 2020 to June 30 2021) the LBUSD received 300 less-than 500 square foot ADU applications and received $461,000 in illegal school impact fees.
