I would suspect that the cost of construction materials and labor are going to be going up rapidly in your market place.

Depends on the type of GC you're looking for.The guys picking up material early in the morning at HD/Lowes/Menards are unlikely to run a very tight ship or handle large scale jobs.

Seems like I have heard that you can make a rough estimate at labor, based on material cost (2-3 times materials = cost of labor). 

Are there preferred building materials that are in use by builders currently?

Materials were very difficult to get, and there weren't nearly as many impacted homes as in houston.

The main concerns that come up right off the bat are timeline and quality of materials/work done. 

Block construction is solid (better than metal but not as desirable as concrete tilt), im assuming it was built in the 70's?

The ARV ratio is 40% and is in line with the data we found during our due diligence process.November 2018 Investor UpdateNOV 21, 2018For the Atlanta Luxury Property Rehab - Final Tranche investment: There have been no material changes to the status of this loan since last month.

@Manolo D. we were definitely happy with the overall outcome. the GC we used did a great job. we plan on using his crew again on our next property if possible. however, I'm guessing you're referring to my other discussion about rehab costs from my contractor. we were happy with the outcome of this project but I don't have anything to compare this to. the fact of the matter is we don't know if his prices were fair for the market. we were in very unique circumstances on the last project where we had flexibility with our budget, so even if he charged more than the competition we still came out on top. moving forward we need to know more details. we are currently making offers on properties in need of rehab and we're using this GC's quote to help us budget for our max offer. if we can use him and still make a competitive offer then we will but we are getting beat by other offers. we just need to analyze all factors to see what we can change in order to compete. the two main concerns are that we are up against other investors making cash offers so they have no loan contingency and no mortgage payments inflating their holding costs, plus they probably have cheaper labor and material costs. so, we're just trying to analyze everything. our GC did a great job, only went slightly over budget compared to his original estimate, but we did plan for contingency and I ended up doing a lot of the work, so we were overall under budget, and he offered the quality of work we were happy with.

You don't use your car to haul building materials in you use your pick up truck.
