Building a 4 unit from scratch is quite the task. Are there no 4 units you can rehab?
If you can find a rehab in the location you're looking for, the money for rehab is readily available and cheap (owner occupied). Even rehab is there for you with hard money, but ground up construction is a lot different.
I don't want rehab properties you never know the exact cost. I want new construction properties to attract my audience. To me buying existing property you have to continue to convince your audience that the properties is under new management. I want my properties to have a fresh start
