There are many scenarios why not ask your lender broker for down payment gift assistance.

With hard money im looking to having to put 20% down payment with a 10-11% rates and 2-3 points 

Here are the details:Asking Price: $181,000Our offer: $170,000Estimated Repairs: $30,000ARV: 275,000We have enough cash for the down payment but not enough for the entire home or the renovations. 

And adding a second unit helps with overall mortgage payments.

I watched a Tracy Z video where she illustrated the "1/2 the note for 1/2 the payments" thing. 

It would be enough for a down payment on a home but being a 1099 employee it is rather difficult to obtain traditional financing.

I’m thinking of asking  30,000 down payment from buyer for them to takeover catch up back payments & monthly note 

Is this considered acceptable or would most want monthly payments in the interim?

It's time to start once you have saved enough to comfortably put 20% down, have enough reserves that you can handle a major repair + 6 months house payment, have researched local landlord laws and rules, have a good idea about what paperwork you will need and have it ready (lease, move-in checklist, background check, etc...), and you've done your research so you know what a good deal looks like.Then the hardest part!

You will have interest income though with each payment.
