If you have no skills as a contractor, I would hire someone that is skilled and offer that person hourly work from 15-35/hour or a daily rate of 200-250 a day for 7 hours of work and a 1 hour lunch for large jobs.Work with them on the weekends as their helper and try to learn everything you can.

I wasnt born this way, I went from zero skill to handy over the years...although I was forced to because my dads a hardass...in a good way haha But if its a cosmetic flip like mine, I would suggest diving in and do what you know you can do and for the things you cant, use the internet, this forum or you tube.

Just saying its a lot of work to do those rehabs and only at the end of day have a 10% cap.These types of properties are what I actually focus on because i have the skills to get them updated.

A good stone craftsman has special skills.
