I went to school in Brooklyn.  

We currently have 10 single family properties in the best school districts and we self manage.

Also illegal for the entire school year, if the tenant has kids in school. 

I know, I get a lot of different kinds of checks because I work with corporations, schools, banks, jobs, etc.

These I have found are real, striving parents, working their butts off to provide the best housing and school system for their children.My ethos in this approach is exactly why we at LaPlante refer to them as Residents, as we consider "Tenant and Landlord" to be dated terms and rife with negative emotion.

Add to that we have Bethel School of Supernatural Ministry with students (ages vary from 18 to seniors) numbering a few thousand, with no dorm space, and investors have purchased homes and rent room space to them.

I’m back now and looking for some guidance on an idea that caught my attention.An old high school friend of mine has been buying older houses, either renovating or tearing them down and rebuilding, depending on their condition.

Good luck, you are a busy man with school, family and baseball.Likely your best bet is house hacking (if your partner and child are willing to share housing). 

I would recommend focusing on good school districts where people want to be, which is going to dictate over average price and rent appreciations. 

After high school, I pursued a career in the military, where I proudly served for seven years.
