It can get plugged up with dirt, pollen, seeds (are there cottonwood trees around?)

I am looking at these new properties in Orlando as 'seed' properties and plan to leverage the equity to expand/upgrade after about 5 years. 

Even if you subtract for RE commission, closing costs and discount the property for a fast sale, you should clear around $50-55k.3 - It would take you around 17 years of perfect tenants to reach $51 k in cash flow.4 - If you invest the $51k in flips, make only 10% per flip, and do two a year, and don't reinvest your profits...just keep reinvesting the seed money ($51k), you could profit over $5k/year...double what you would be getting in CF if you left it as a rental.5 - Now, if you reinvested your profit back into the flips, you would be compounding you profits.6 - 10 years of compounded profits, at 10%/flip...2/yr = over$280k in profit7 - After your accumulated profit reaches the point when added to the original seed money equals enough  to when flipped, you can use just the profit to buy rentals.8 - keep flipping the enlarged seed money.  

Then use a public facilities Bond Program Project that can be managed with public funds which you seed and manage.  

I would avoid unless there is a seed of gentrification.

Use the initial seed money to continue flipping. 

Start planting seeds

Trying to find a means of a side hustle would be ideal at this point to create more seed money. 

If not, you've planted the seed in their mind about selling the property.

Having to follow through with executive decisions is much harder due to the deep seeded personal relationships with these people.
