I'm also very open to meeting other investors and to exchanging ideas. 

@Jade Frank I agree with what @Dominic Mazzarella and others are saying here, but If you find the downside outweighs the gain and you ultimately decide to sell the property, Since the property was held for investment use it would qualify for a 1031 exchange. 

You’ll get a better return over the long-term by putting your money in the stock market.

I don't have a lot of experience, but I do have the ability to exchange my time, so that could be a form a currency that benefits them. 

If you do sell I would do a 1031 exchange We do need the cash to buy another property. 

If a unit is significantly under market rent and needs upgrades, offer the tenant an upgrade in exchange for a renewal at a higher rent.

After a year or so they then sell the property and do a 1031 exchange. 

Popular choices like Fidelity, Schwab, or Vanguard let you invest in a range of stocks, mutual funds, and ETFs.

If you do find that the costs to maintain the investment property are too substantial and you'd rather sell down the road, it would qualify for a 1031 exchange since the property was held for investment use.

This works with any type of appreciating property such as real estate, stocks, etcDepending on the appreciation rate, you can potentially see asset values double every 7-14 years.Likely around 7 years if the appreciation rate is 8%Likely around 14 years if the appreciation rate is 4%If you buy something for $100,000 and it appreciates to $200,000, you can potentially take a loan on the $100,000 appreciation which would not be considered a taxable event.However, be mindful that you are paying interest on the loan and you have to payback the loan but yes, it would not add on to your taxable income.
