In my opinion, responding 5-10 hours is not unusual in this industry.

i know a lot of old school PMs just have never done things in the way that many do now, with software like appfolio and such. if i know and trust them, and they're amazing otherwise, and there aren't any concerning numbers on my properties, and i know other investors who use them and have great experiences, i wouldn't worry but would ask that we meet in the middle with expectations on this. but if that is NOT the case, i'd probably worry. i don't think it's unusual for repairs to be 30% of the gross rents one year, especially if it's your first year owning it and the previous owner didn't really take good care of it, but if that's the avg over multiple years of ownership it doesn't really sound normal. however, is that 30% inclusive of ALL operating costs?

This price will of course be higher if you have an unusual roof design with greater surface area. 

And if you have a problem with a tenant that has been there several years, and suddenly you want to inspect, that might seem unusual, and cause problems, where regular inspections are then expected.As far as yearly, or twice a year, that is up to you, but just remember that the earlier you catch a problem, the cheaper it will be to fix it.

It's always a good idea to keep thorough records and be prepared to support any changes made to your tax return.If you're uncertain about how to proceed or have concerns, consider consulting with a tax professional for personalized advice based on your specific situation.

I'm contemplating making updates to the property but am uncertain about the return on investment (ROI) I would receive.

So they have this property tax owed information, but not older tax liens, so I'm confused or uncertain.  

Then General Partners can share in profits.It’s not unusual for syndications to roll over a balance right into the sale of the property.

The temperatures have been unusually low and pipes in the home froze for 5 days so far, making the house unusable as a short term rental.
