After the first year I plan to acquire some rental properties for a more passive income stream.

It is always a pleasure to network with other Orlando investors.As James Wise mentioned, building a rental portfolio using leverage is a great way to build an ongoing cashflow stream.

But if they do, you get to keep that revenue stream, and access your 401k money.

With all this being said, I still have a lot to learn, but like in typical real estate, its very difficult these deals to find a steadily stream of good deals.

This allows you to keep your current set income stream, get started with less of your own money down, begin learning by doing (which is always better than being stuck in research mode), and you STILL live rent free because tenants will now be paying you rent to cover your mortgage, expenses, and then some.

A couple years ago I changed course and started doing new construction projects, it still is a new kind of exciting and can be very lucrative (maybe possible without changing markets).I have more recently began looking at diversifying income streams - buying a business, investments outside of real estate, etc.Ultimately it comes down to what gets you going, maybe time to bring someone on to handle the items that you dislike? 

Passive income stream to supplement current retirement income.2.

A $90K investment results in a stream of 135 weekly payments of $1000.

The exceptions are historical value, intrinsic value (for example, it you built using solid gold fixtures) or some other value the building or land possesses over and above the income it generates.In terms of measuring the value of the income stream, there re lots of compliicated ways to determine that, but it all boils down to these two formulas:Net Operating Income (NOI) = Gross Income - Costs/ExpensesValue = NOI / Cap RateSome very, very, very generalized assumptions you can make for a first pass analysis are:- Costs/expenses are between 40-60% of gross income- Cap Rates are between 8-12% in many parts of the countryUsing those two very gross assumptions, and using your income number of $125K, the value of the building will likely fall somewhere between about $500K and $1M.It's unlikely -- given the info you've provided -- that it would be worth the $1.2M you'd be spending.

Ultimately the goal is building a portfolio for passive income stream.
