New to RE investing, finishing my first year.

[Geren Knight III]

I am just finishing up my first year in fixing and flipping. Things went fairly well. I joined another investor who had been in the business for a while. We are two weeks away from closing on our property. We purchased the property for around $30,000 with an ARV of $125,000. I have learned a lot of what to do and what not to do, especially when dealing with contractors. I'm planning to purchasing rental properties. Does anyone have any tips or dos and don'ts for me?
