I'm in NE Ohio and while I don't plan to completely "self-manage" (ie, do maintenance/cleaning/etc. myself) I do want these properties to be close enough that I can A) check them out personally when needed and potentially tinker/add improvements on occasion myself AND B) if they are vacant for a weekend, go and enjoy some R&R on short notice. 

[Hint: At least 2 years more, and counting].Solution? 

I have a small air BNB that takes under an hour to clean. 

Then complain they smell and need to be cleaned.  

I think I need to start by clearly offering the rent solution and then working from there.

A stable female single mom, 6 years of renting, never late, always clean, gets with a 'fun' guy, good job, accepts her kid.  

I'm looking to see if there is a creative solution to this.Can I build a ‘detached’ house along the property line without any windows on the property line side similar to how it would be if I were building two attached houses side-by-side on these lots?

If you're familiar with Microsoft Excel or Google Sheets, those are going to be the easiest solutions to build a customized tracker for your portfolio.

There are plenty of threads in this forum and on YouTube to understand the solutions.
