I'm 24 and I'm lost!

[Ricardo White]

I have no clue on how to run comps and or calculate ARV or rehab cost. I do have an example of a deal i was working on that I think I may let go because of to much red tape associated with the deal. I'm not asking anybody to do the work for me I think if I figure this out though I'll be well on my way.

1312 South Roxboro Street Durham, NC 27705
Tax Value $62,856
5/2 1,936 feet full basement
8,000+ sq ft lot
has code violations due to the fact it was built in 1925 and is "basically" condemed needs complete rehab but I'm not sure if there are foundation issues/major plumbing issues. The house is located on a main street however surrounding streets aren't so great. I've used sites such as Realquest Express and Zillow but the estimates were so different on value that I really have no clue.

The seller is asking for $45k which in my opinion is too high but she was quickclaimed the deed by her son who owes 20k to my mother (lienholder) HE NEVER PAID A MORTGAGE PAYMENT not sure the details of the originial contract as my mother is ill and can not find it.

In the future I'd like to be able to acurately figure out the ARV and rehab cost on property so I will know how much to offer to potential seller. I am only 24 and my knowledge is not extensive just what I've learned through internet articles and youtube videos. PLEASE HELP not trying to be greedy just trying to help family out, do something I've finally found that intrests me, and pay off student loans!
