One out of the box idea that might be cool is to implement an educational feature similar to learning a new language on Duolingo.

You can get an idea yourself looking at comps in the area.

Any ideas on what to do here? 

I had no idea who we were working with as I was lead to believe it was one of his clients from his tax business.

Certainly nothing ground-breaking in terms of ideas here, however I'll be very hands on (and on site) during the process to make sure that every step of the way is executed to a high standard and very carefully.Once I've hopefully developed a successful track record and gained experience, my next goal would be to move on to commercial assets (think multi-family, industrial etc) so that I can leverage my existing investor network and real estate knowledge to raise 3rd party equity and take on bigger projects.

I’d love to connect to exchange ideas and experiences. 

So I rented it out via agency I as loosing $300 a month since my mortgage was look the idea was to refinance to get it lower or sale it when market is up.

This is why renting to family or friends is generally a bad idea.

I got 800+ credit and great mortgage offers so only reason im doing this seller financing idea is that its lower monthly cost

Both are great ideas or even both.
