Carol gave you good advice. If you want positive cash flow, work backward. Start with how much cash flow you want. Then add in the costs of holding the property, including a mortgage for the whole selling price. Subtract this total from the rental roll, reduced by a reasonable vacancy factor. If you have a negative number, your mortgage payment is too large. Reduce the purchace price and mortgage amount to reduce the mortgage payment. When you have a zero difference between the cash flow and the expenses plus profit, that is the maximum price you can buy at, at least with those rents, costs, and mortgage terms. Just be sure that you have really included all the expenses. If you have a “set-up” sheet from a broker, it may well leave out some expenses, such as reserve for major expenses. Sometimes they leave out taxes or insurance. It is incredible what you will see in set-up sheets.
