I have had various avenues of exposure to the stock market, and I continue to manage three portfolios right at this point. 

Just think about it - before Charles Schwab, you would call your financial advisor/broker and pay $200 to sell/buy a stock.

We don't keep properties in stock, we work with each investor on an individual basis to identify properties that meet their investment criteria and manage the asset at their direction.

$12.5k - vanguard total stock market index fund$12.5k - keep in cash $25k - downpayment on sfh

Also the housing stock is generally in poor condition in the city, and you have the typical problems that come from low income areas like crime, drugs and violence.

I use that as an example though as I dont like the low quality of tenants and housing stock in Chelsea, though I have owned properties there that Ive sold in the past couple years. 

@Jesse SmithCaleb is correct that you will pay capital gains tax on the "gain" which is selling price less adjusted basis in the index fund.Do you have a considerable gain from the sale of stock?

I’m currently 18, and I am looking to start investing in real estate to supplement my stock portfolio.

If you will accually make offers to buy, lend, wholesale, etc. with your account, you will crush the average stock market returns.

Being  a versed stock market enthusiast, I began to do a little math one morning for ***** and giggles while I smoked my cigarette and drank the 1st cup of coffee for the day....
