That being said, it might cost you a little more than subbing each trade out but you're likely to make up for that cost on the sale and the time you save by working within established relationships.If there are any major issues with the project you're looking to take on you'll want to take pictures if you can so you can send them in advance so any contractors can bring the necessary tools to assess the scope of work.Take a quick look at the materials you're going to need for the site either on Home Depot or Lowes or something similar so that you know roughly what the cost of materials is going to be.

Establish connections with other local experts, realtors, lenders, contractors, and investors to get knowledge from their experiences and cultivate a network.
