@Juan Carlos CorreaLet me know if you need any great general contractors and I have large network for this area. 

I am getting a lumpsum estimate for things like electrical, plumbing, but I am not sure what the cost is for. 

What I do for my units with shared meters is I charge 50% flat to each tenant which prevents waste I get no issues with any waste due to this but the ones that share electric bills do get many complaints due to the size of the bill.

So - As a PM I do free property analyses for people who are current owners or are people under contract or even just see one that catches their eye. 

Here are a few tips as you step out on your own: Attend local REI meetups and events in DFW to connect with other investors and contractors.

I'm a San Antonio native and I am also a Project Manager/General Contractor.

I'm a general contractor and only do network marketing so I could help you out on a few things.  

We had some other work done by contractors.

I mean let's be real, about 80% of the complaints investors on BP have about their property manager, contractor, turnkey co, Realtor etc.... are just nonsense.

I would find a good realtor, use Kiavi or wild-cat for lending, and good contractors through your realtor, and a local PM.Then you can re-fi using a DSCR loan and leave very little money in the deal and have it cashflow.
