Yes I could do a generator but that is more bother, tell the tenants to turn on the fireplace.  

Social media has really messed it up for my generation.

The goal is legitimate: due to complex tax rules, you have opportunities to game the system by selling some of your investments and intentionally generating either gains or losses.

We don’t plan to leave jobs and live off of the portfolio but have it as a wealth generator aka hedge against future risks

Not enough people to generate the demand to sell enough houses for that size property and not enough people for a factory or something to come to because they wouldn't be able to get enough employees from the surrounding areas.Is that a good hunting area?

However, vacancy means covering 100% of the expenses.Multifamily properties almost always generate higher cash flow due to multiple income streams, which also reduces the risk of vacancies.

Let’s say that the sale generates $300k profit for simplicity.

Quote from @Jinglei Shen: I am building my investment portfolio(duplex) in Ohio Cleveland, a few properties i have analyzed  with net cashflow  around $100 to $290 here is one deal I am analyzingDuplex generates $1590 income /month together,purchase price $123,000rate 7.5%, downpayment 25%5% vacancy, 10% mgm fee, $1400/year insurance,10% capex, 5% maintenance,COC is 8.73%monthly net cash $277this deal meets1% rule, bring in positive cash, my question is it in normal range in Ohio Cleveland market? 

The answer is to value this as any other business generating income, not just stick within the confined box of valuing the real estate only.  

Then use the extra roommate rent income to pay down your mortgage and look to refi to a lower payment in the future (3-5 years) - so it cashflow when you move out.You could also choose the smaller unit and STR the other unit to generate more cash to pay down your mortgage and refi, so it cashflows when you move out.Bottom line: you'll have to get creative to solve your cashflow challenge!
