$50,000 available for Down Payment 

I just had a bank tell me that per new Fannie guidelines, the minimum down payment on a 3-4 unit is 20-25%, even if it is bought as a primary residence.

To structure a partnership, consider forming an LLC where you handle property management, renovations, and operations, while the investor provides the down payment.

Some of the discounts are good, but just be aware that you will be paying a payment processing fee on top of the discounts. 

These are typically interest only and require a payment of 1-4 points up front depending on your area and the PML.

Although you have to wait for payment with a 203K loan. 

In theory, since we don't have a prepayment penalty, you could borrow the money, complete the rehab and pay off your loan before your first payment was due.

I have to think this is not his software but a white-label offering.

This reduces your housing payment and helps you build equity. 

We saw huge appreciation in the 2018-2022 inflation run up, but that has significantly slowed these days in my opinion.From a rental perspective your monthly income per unit after all expenses with a typical 20% down payment is likely $100-300 when you find a property that will cash flow.
