@Jonathan Batson, First question to answer yours is; Have you purchased the best 2 books for a new investor to learn about purchasing and rehabbing homes is from @J Scott, The Book on Flipping Houses and The Book on Estimating Rehab Cost" . I love these two books and have probably sold 25 copies of each for J Scott. Read those two books to learn where to gain the information on costs. Ask some people in the business at a REI meetup group who you can get with to go with you to do walk thru and ballpark these repairs. If your deal goes through, he can do a more detailed evaluation during your inspection period. Look and Listen & Learn. Finally, get the big box stores like Lowes, The Home Depot apps, whatever is in your area and look up costs of supplies. You will gain a knowledge to do your own walk through for the initial cost to rehab. And last but not least, When you receive your first scope of work rehab cost, double it, if the deal works you will be okay. This is until you can walk through a home and estimate the costs in your head and be correct. Best of Luck to You, looking forward to seeing your success.
