I’m sure you won’t be verbally assaulted about how greedy you are Basically they were gifted $60-$120k tax free. 

This is basic stuff you missed. 

Long story short, it has been over a year and the project remained incomplete and he walked away with the money.

- The market is in a little bit of a lull right now (buyers market), its a great time to buy, but slower time to sell (my primary business is flipping houses) I can supplement my flipping business by providing project management services/consulting, helping investors find discounted properties, etc. etc.

Another possibility could be a home equity line of credit (HELOC), if you have sufficient equity in another propertyGood luck with your project!

Also I'm working on a few commercial projects at the moment as well!

It balances stability with potential for appreciation, especially if you find a reliable tenant.On the other hand, for investors with time, experience, and a willingness to take on higher risk, active strategies like value-add projects or flipping might yield quicker returns but require deeper involvement.
