might make more sense for your nest egg.Regarding timing, I’d refer you to Jeremy Siegel’s point in Stocks For the Long Run. 

In my particular market of high end condo conversions we are looking for tech based units such as Nest and surround sound features, pot fillers and wine/beverage bars in kitchens, and heavy doors and more luxurious hardware throughout the house.You should do a tour of a lot of properties in the condos/homes in that area and you'll start to get a sense of the theme of what the consumer demands in your particular market. 

My fear is that I might stir up a hornet's nest and have an even harder time getting my CO.

Currently New Jersey does not allow you to form a (S)LLC in the state; however, I know many investors who form the Series LLC in other states and have their properties nested within the (S)LLC.

If you are ok with waiting until you are 59 1/2 years or older to have full access to the 401k contributions and gains (penalty free) than your path might look different than someone who wants to have a monthly passive cashflow that meets or exceeds their monthly expenses by age 40.Trying to amass a large nest egg in financial products such as a 401k, IRA, etc will require you to save & invest 50% of your income to gain 1 year of paid expenses in retirement, which assumes similar health status and lifestyle choices once you get there.If you are interested in economic independence earlier rather than later, invest only the 5% to get the full employer 401k match and then focus on positive cashflow investments to start replacing your active income (your job).

Buy your own home and get away from the nest.

If you have excess income and you want to use it to try to build a nest egg for retirement, rather than spending it, then you probably want to invest in something.

We have Nest Thermostats installed and some tenants like that when we show our units. 

., if they are extremely energy efficient.If higher quality property, consider installing nest thermostats to help with energy savings since tenants won't care if they aren't paying the billI'm sure there are many more but those are a great place to start and get the bulk of your savings. 

But I’d like to come back with already a few doors under my belt, kickstarting a career switch “nest”.Which kind of difficulty am I looking at to start with the first property from a distance, then to eventually have around 30 by the time I get back?
