Just run numbers in a BP calculator.

I am 100% real estate development in my business so these are calculations I need to make all the time.

You want to delegate all the mundane tasks to others and focus on doing tasks that only you can do.While you are calculating the costs of all the raw materials, you also have to calculate your salary into the total cost of writing your own handwritten letters.

We have quite a few resources here such as our STR Calculator, STR Newsletter, and our bookstore which has "Short-Term Rental, Long-Term Wealth" that is excellent.

So, I am looking at postings near train stations in NJ, but often I am getting negative cash flow when doing calculations.

Does anyone have any idea how to calculate or measure risk on something like this?

Since it says you are new to real estate and sharing calculations, my experience is that a lot of new investors are spending a lot of time "modeling" and zero time actually seeing homes or multis or commercial properties in person.

In 2023, gross ROI for flips averaged 27.5%, but net ROI (after all costs) is usually 10-20%, calculated on the total investment (purchase price + repairs).
