I am commenting so I can be updated… the only advice I can offer bud is when you do your HELOC open up a separate bank account move the funds of the HELOC into your private account and then transfer it into the account for the Duplex that way when it comes for taxes you can write off the interest payments for the HELOC.

PMI (private mortgage insurance) is the mortgage insurance you must pay with any other type of loan with less than 20% down. 

How much private equity can be used to purchase a roughly 3 million dollar multifamily unit? 

Do note though that if you just become the pushy agent trying to get clients all the time everyone will privately hate you and it won't help your business.

You can borrow from friends, family, private money or hard money, then refinance. 

Maybe find a local private lender (self-directed retirement account) that will lend with not much underwriting.

Private loans and a traditional mortgage How did you add value to the deal?

@Chris SeveneyThe Socialists use COVID and the like to pass legislation to weaken property rights and further their agenda of destroying private property and instituting state property ownership.In 1947 NYC, using the post war housing shortage as an excuse, instituted the “temporary” measure of rent control. 70+ years later the temporary measure, as well as a companion measure instituted in1971 is still in effect, with the effect of having provided a transfer of wealth from property owners to tenants.

Just do a private sale/purchase between yourself and your parents and use financing. 

I have about $10,000 to get started so I'll have to use private lenders and/or hard money to get the first deal going.
