Any have a spreadsheet for evaluating the possible ROI on a Turnaround Park - that I ALREADY on and

I realize I rambled in a previous post and wasnt very clear so sorry about that.

I have this old MHP for years as solely a buy and hold. It has not been an operating mobile home park (even when I bought it).

So I need some form please that I can plug in expected costs of bringing in homes now, slowly upgrading water lines one at a time, rent coming in each month etc…

Most forms I see are only for the purchase of a turnaround park. Or just buying a park in general.

I just can’t find anything on a property that one already owns.

Please help as I have to lay all info out to my banker very soon to ask for loan or credit line againsg the equity .
