I love that you have found passion in REI and have laid down a path to success with your three approaches.Of the 3 activities you are in, do you prefer one over the others?

That can be tough when it's a one-off job or you only have one rental.

How many new developments can you execute in one year vs flips?

The deals not going to get better because of the questions you ask, but we look for three main things from an investor: 1) Liquitity/Financial Assets, 2) A good credit score, and 3, and this is a big one, Experience.

Quote from @Will Greenlee: I would agree with @Drew Sygit every software has its kinks and this one along with all the other ones started somewhere.. 7-8 years ago Buildium was less effective than it is today, and now it is a lot better.

It all depends on the work you/your clients want to do to create value and the overall game plan.

But did create issues of determination of value when distributing the assets of the LLC because all properties are probably not exactly equal in value or equal to a members % interest.But either of these can be made to work for you in the situation you describe.

Bottom line is - pay for the expert advice on this one.
