I’m looking to invest in a portfolio of multifamily properties to eventually replace my full time income.

Nevada has no state income tax and the 4th lowest property taxes in the United States. 

Which I would think is surrendering the rights due to the inconsistency of income or no income or wages? 

Indeed, and depending on a variety of factors you can even use them to offset your w2 income 

So I posted the other day asking if I could get around passive income on my rental properties so I could contribute to my retirement account.

We see the average Sect 8 tenant occupies a unit for 7-8 years before making any moves reducing turnover costs.  

Census data - median household income, employment stats, bachelors degree percentages, crime, vacancy rates, appreciation2.

If you're at a loss and paying off the shortage still puts you at a loss I think your best bet is selling, or seeing how you can get more income from current rents by making it mid term/seasonal or an air bnb. 

The only method that really comes to mind is BRRRR, which I am not opposed to, but would prefer something a little simpler for a first time deal.Similarly, I'm making an assumption that it might be possible to use a combination of HELOC and DSCR loans on something a bit more turnkey for the initial purchase and then refi into conventional after a year or two rental income?

This means that they are going to look at the ratio of the Net Operating Income (NOI, or income - expenses) divided by the monthly debt service (your monthly payment).
