I'm thinking you need a split A/C system. 

I don't think age is ever a factor, but knowledge and self control will dictate everything.

In addition to being the IT Director for our local county government, I am also well versed in geographic information systems (GIS) as a data analyst, and am a Certified Floodplain Manager.

As with any/all information you see online, this is my system and what works for me.

Background:-Changed from systems/software engineering a year ago into IT Management.

It''s the only time you will get to buy and control 4 units with just 3.5% out of your pocket. 

But just one deal, little likelihood they will catch wind.I only bought mobile homes on their own land, where you control the entire deal.

Is the community not participating in flood controls as a whole?  

In 2-4 years I'd like to expand that to include single-family residences and land.GOALS: Replace my income with positive cash flowHouse hack (or not) in all the places I've wanted to live in the US (and maybe abroad) as a means for growing my portfolio after my income has been replacedDevelop really great relationshipsBuild a system that can work with minimal input from meMaintain frugality (MMM)Change my lifeLongterm - Invest in neighborhoods that need a liftLongterm - Provide shelter for homeless families and runaways
