Where you purchase a property that needs some work, live in it for 2 years, fix it up (either DIY or hire contractors), and then refinance & rent it out.

You're welcome to donate to my Venmo - otherwise - enjoy the fruits of my labor :)  1.

And half the time I catch something, even with contractors we have been working with for years.

My main concern is that the contractor does not extend past the 3 days and take any time off for weekend.

I have a friend who works for a well-renowned construction company in our town who has offered to be our general contractor at a discount (only charging us 8% vs. the standard 15%) and "teach me the ropes"/make the right introductions so that I can repeat this on my own in the future. 

My concern is obtaining a construction loan without a contractor's license. 

Cash-out refinance a few like @Joe Villeneuve mentioned and enjoy.

I enjoy remodeling and updating projects and would like to create another source of revenue from my 9-5.

Enjoy the weekend! 

Partly for the strong casflow that we enjoy after 30+ years investing along with other reasons.I would probably not buy additional property all cash, but improvements and betterments will be paid in cash or at least quickly.Leverage is a great tool when used properly.
