I want to become a multi-family investor to achieve financial freedom.

A HELOC can work for this, but keep in mind it has a variable rate, so it isn't the best product for keeping a balance long term. 

These relationships, if cultivated properly, will allow your borrowing to outpace your balance sheet.

I am a Realtor and have a seller that has an assumable loan, but that still leaves $300K between the balance and the sales price.

•Financing challenges: Extracting equity and taking on new mortgages require careful financial management to avoid over-leveraging.My Questions 1.Do you think this plan is realistic and achievable?

But that's what investing is.....deploying capital to achieve a return based on risk.

In a simplistic metaphor, the FED needs to balance out the health of the economy with inflation.

Yeah, we both want to have the tallest buildings, but we don’t have to tear down everyone else’s building to achieve that.

Do you have a family member or friend who's achieved what you want to achieve?

Using the 50% rule (taxes, insurance, Capex, maintenance, vacancies, property-management), that should give us ~19K/month in pre-tax profits that achieves our 10k/month financial goal after-tax and adjusting for inflation.Our assumption is that building new-construction would reduce capex & maintenance the first few years.
