Maybe your landscaping guy and painter and roofer and handyman give you a little break if everything is close together.

I also have side work framers and roofers that we call occasionally and we have a go-to local plumbing company and HVAC guy for emergency maintenance calls.

Bookkeeping is no different than hiring a plumber or roofer. 

So far I have built a team that consists of a supportive girlfriend, two lawyers, a property manager, a general contractor, electrician, plumbing and HVAC guy, roofer and tree guy, window guy, real estate agent, and insurance agent.

I had a roofer caulk around it but he says it needs to be repaired.I haven't had the ducts cleaned in some time. i do use the cheap filters; i've been told countless times the cheapest ones are the best, though i am not sure.

It shocks me that they're in the business selling investment real estate and don't own any themselves.Experience does help.I would also say a great list of vendors also helps....carpet cleaners, roofers, painters, handymen, lenders, title companies, and 100 others.Who is best PM in town?

A roofer sees step-decking and waits until all shingles are off the roof to tell the the owner that they need another $5k to replace the decking with plywood.

I had not replaced mine yet as my roofer was a little slower, so I got 2 for 1 storm damage.  1 roof 2 storms.   

You'll find tons of contractors at your local reia, and I would suggest for your first flip do not give all work to one contractor, roof to roofer, hvac to hvac, flooring to flooring etc.

Have you called roofers in the DFW area to get quotes?
