So I get your hesitation to be too demanding and your desire for the problems to go away as fast as they can, however since you have NO property manager ( I don't use one either), it is incumbent that you take a more ACTIVE approach with management of your property.Let's review your situation.  1st time leak occurred, you sent a plumber over to find the problem.  

I did notice end of 2024 to be more active and January to continue that streak compared to 2023 and start of 2024.

I am not sure how active his company Open Door is on BP.

Upon further review, there is 1 active Type 2 STR permit on this blockface prior to your STR application submittal, but a system glitch did not capture it on the OneStopMap.

Looking to be an active investor or passive investor in a deal? 

Cincinnati and Columbus chapters are very active here and nationally and a great resource for networking, recommended contractors/vendors and education.

@Eric E.UBIT only comes into play in an IRA on leveraged real estate and running an active business.

Most who get tripped up are those buying the smaller multi-families that don't possess the correct use permit/historical rental license activity. 

I live here and I haven't seen more FSBO but I'm seeing a lot more wholesaling activity.  

If the investor is actively involved and can stay on top of materials, roll with it!
