You won’t find many seller-financing deals here, so if you're looking to scale quickly, your next best option is the BRRRR method—using cash or hard money to acquire properties and DSCR loans to refinance into. 

In this case, your monthly payment with 20% down will have a good MARKET rate if your DTI works with a much lower month payment and no mortgage insurance(MI).

I’ve done some research and have found that some banks will allow the seller finance portion from the seller to go towards the down payment of the loan, is that true?

.- There is no discount or created equity over and above the amount that is used as the down payment for the home.- The management company charges a management fee of 10% - 15% which can be a little higher than average property management companies, but that cost may be offset by higher quality of services.- The management company also charges for other services such as fee for coordinating maintenance and repairs, and turnover and releasing.

Or a seller finance calculator showing the monthly payment based on negotiated price, interest rate, down payment, etc.

The strategy I'm following for my first house hack is to acquire a multifamily property (duplex, triplex, quadplex) or SFH w/ an ADU (or potential for an ADU) as I am mainly looking to simultaneously acquire my first property and subsidize my mortgage payment.

To make a long story short, they are no longer able to make payments on the property and are in danger of losing it.I have a rental property in Southern California that I currently own whose value if I sell should cover the outstanding loan balance on the farm.

Risks: rates go down and you have to pay a prepay of 2 or 3 %; you have to sell and pay the prepay; rents decline & you can't make the payment like any other type of loan; cost upfront a little more than conventional; need to find experienced broker licensed in the state where subject property sits; servicers are bulldogs. 

Then if/when another good deal comes up, you can approach a lender and look at leveraging either of the properties in order to fund the down payment of the new property.

Also, it often helps to connect with a local agent/do extensive due diligence on renovated/new construction properties to see what the property may sell for or appraise for (if doing BRRRR method) as that can impact the price you should pay.
