Thanks again guys...just did some calculating (bankrate.com actually did). Been talking with my dad who just retired and was looking to get me to invest in mutual funds or something along that lines with a 7% return or so.... so here are the numbers:
$300,000 invested over 15 years at 7% equals $827,709
$300,000 invested into 15 houses ($100k each, $20k down, 4.5% for 20 years) = $806PITI (here in DFW area of Texas). Say it rents for $1100/mo but we round down to $200 cashflow due to vancancy and what not.
$200/house * 15houses * 12 months = $36000/yr income * 15 years = $540,000 with each house having a balance of $27k. So $100k house - $27k balance = $73k in equity * 15 houses = ~$1.1M + $540k income = $1.64M after 15 years...
So roughly double the 7% investment... sounds like a no brainer? Hopefully pulling more per door and reinvesting into more properties to compound the earning on real estate. After the 5 more years, the income would be $15k a month as passive income. Just wished I started this earlier
