Check how many electrical meters there are, and if there is one for the common area. 

I found a contractor that was on the list of vendors for one of the Bigger Pockets realtors. 

I understand that rents and flips will have different criteria's of renovations and that I could always get a contractor to go out and get a quote; however, is there a way to learn on my own and be able to analyze how much a rehab will cost just from walking a house and going to a showing. 

I know its expensive but you will be well protected :)Or you save a lot of money and be better protected by doing this consistently and well:-carry appropriate types and amounts of insurance-sign contracts with indemnification provisions- obtain all necessary licenses and permits to operate your business-ensure all vendors/contractors are licensed and insured and list you as additional insured-sign well drafted and fair leases and be a responsive landlord -be an active owner or hire an active PM  who avoids or at worse timely eliminates premises liability exposure The strategies you often read about are sold by alarmist asset protection companies who fail to disclose how impractical they are.

I'm having contractors over the next two weeks to see the project and bid on it. 

Ultimately, my vision is partnering with a private lender so I can spread my funds across multiple deals at once and scale quicker; I'm really happy so far with my agents, contractor, and refi lender, so I feel like getting a great lender would be the next step for me.

Narrow down to one then build your core four of a realtor, lender, property manager, and contractors.

I am contractor in Toledo Ohio.

We have contractors that are supposed to start in 3 days so my family can move into the house in a month. 

Its a little more expensive but when our tenants put in maintenance requests we can simply forward those to our contractors.
