I know that compound interest would play a role in the 401(k) gains, but I would also see it in the real estate market (more properties/more income/more doors/etc.).

ok so NO I DO NOT think you should consider buying this home.... first of all i think your numbers are off, insurance on $500K home is way more than $50 a month...also you will need 20% ($90,000) for down payment if purchase price is 450,000......then you also need to consider other expenses like vacancy, repairs, property management (even if you self manage)..... as your first deal this is way too much risk for negative cash flow and the hopes of appreciation........if its still sitting on the market, then its over priced....... an appreciation play is not a smart first investment IMO

My question is what online courses can you recommend for me to get a license or school in miami,fl ?

I’ve been shopping around, playing with the numbers as best as i know how but I’m starting to question if I am in the right place to make this sort of investment.Background story, I just bought my first house November of 2017 (bought at 15K less than the asking price and about 45K less than the appraisal value).

Also, I'm not trying to be "that guy" online.

I’d like to collect the rent online or through something like PayNearMe, but I doubt they're online savvy.

Have you searched for them online (found one of mine in Plano just outside of Dallas and am thinking of filing a foreign judgement with the clerk of court there).

BP is one of the best online real estate investment websites.

I will go online and find out the cash flow of properies just to practise =) BiggerPockets do have the propper calculator  for this but i have to be ''pro'' to use it... 

I'm glad to be joining this online community and look forward to contributing based on my limited, but growing, experience.
