Jack, you are not paying for the text your write so be a bit more forthcoming with the information. There are a number of options for 7 houses on one lot. Hard money which is borrowing from people who lend on the value of the property and charge high interest rates (10-15%) and high points (1-5). You can get a commercial loan from a local bank or credit union. You can get a business loan secured by real estate from a local bank or credit union. You can borrow from a rich uncle. You can partner with another investor and give them part of the deal (part of something is lots better than all of nothing).
With banks and credit unions you have to call every one of them and get hooked up with the commercial loan division. Small banks tend to do better with this than large ones but you have to call them all. When you get a no ask who might. Ask other investors who might lend on the deal. Network network network.
Let us know how it turns out.
