Any trouble shooting advice?

They immediately troubleshoot with a tenant and then will dispatch immediately if the issue requires immediate response!

Not only can you get a service to take calls, but they'll put an experienced tech on the line to troubleshoot with the tenant.

I agree, as engineers we develop a lot of analytical & troubleshooting skills which I feel definitely apply in REI.

However, there was no troubleshooting done.  

I don't know about cost as we do our own inspections in Dayton but he's been very helpful to me and many other investors troubleshooting issues.

He was a pretty chill guy and I had two other roommates who couldn't stand it when we'd be on the phone with him troubleshooting the water heater or some other appliance and we would inevitably be fixing it for him while he talked us through it.

He/she will be able to troubleshoot you if you ever have a question.I also agree with the above, I would use the desktop version of Quickbooks if you can.You can get a version for $200 that will last 3-4 years.People are also using Stessa 

The GC will have a lot more connections to subs and will actually be able to gather more and better pricing for you as some subs won’t even bother pricing to “one off developers”. 2) GC’s have systems and all kinds of document templates in place to deal with all the usual items that come up managing construction projects. 3) They should have a superintendent that can troubleshoot the drawings before the issue comes up on site.

Regarding the bookkeeping, you might want to see if they provide software training and troubleshooting to clients that opt to keep their own books.
