It sounds simple but it can increase costs and delay construction which kills a budget.   

CF at current rates after all actual and budgeted expenses would be 80K a year for four rentals. 

For example you won't have repairs every month but at some point you'll have a $1k repair and if you've budgeted $100 for monthly repairs you'll be fine.

I have an older truck that I am using as I remodel my property. 

For the example above the lot was sold for $800K+, which further reduces the budget left for construction (demo existing property, clear the lot, excavate, etc.). 

Construction cranes and concrete trucks are literally everywhere, with both commercial and residential development.

As others have alluded to, I think it is a good idea get all of your team in place so you can confidently move on properties as they arise with as accurate of budgets as possible.

You don't have an expense for that.Always include a budget for initial repairs.

Now you could buy your investors out or sell it to another entity you own but you would need to disclose, check the operating agreement, and then meet whatever returns you budgeted to the investors. 

We were able to get their offer accepted and the house is going to work for their purposes, it meets their goals, and is under budget, but it certainly was not what they were originally looking for when we started the process.
