I've been able to get a healthy combination of both cashflow and appreciation from all my properties after a little TLC.

Even with the possible down payment gap, it's imperative to thoroughly review the figures to make sure the investment is still financially healthy.

But due to 10 Tech giants , our economy is surviving and seems "healthy". 

Anything which injures health, is indecent, offensive to the senses, or interferes with someone's free use of property can be a nuisance.

A sociopath is immune, but most people are not.

A healthy percentage of higher density multi family properties are open to seller carry or owner financing.

Depending upon that, and your financial health I would just recommend hanging tight and adding another avenue of future income.

For example, a 40-year-old healthy male might pay around $500 per year for a 20-year term life policy with a $500,000 death benefit, compared to $4,000-$5,000 per year for a whole life policy with the same death benefit.

These are the sellers OFF market that may accept a healthy discount, but these houses come with issues that may be cheap to fix or may be very expensive to fix.
