Or put down like 20 percent and use debt to go ahead and maybe purchase another property?

& in keeping with that...In the United States, 70,200 people died from drug overdoses in 2017, which was an increase of about 10 percent over 2016.

https://www.har.com/content/newsroomHouston Real Estate Highlights in July:-Single-family home sales jumped 11.6 percent year-over-year, with 8,953 units sold – the greatest one-month sales volume of all time;-On a year-to-date basis, single-family home sales are running 3.0 percent ahead of 2018’s record pace;-Days on Market (DOM) for single-family homes edged up from 48 to 50 days;-Total property sales rose 10.9 percent, with 10,478 units sold – the greatest one-month total property sales volume ever and only the second time in Houston real estate history that the total has surpassed 10,000.

I would start way lower, and try to get it on a 5-5-5 deal.  5 percent down, 5 %, and 5-7 yr balloon.

@Theresa Harris I agree 100 percent 

Put a lot down and have cheap payments on my first duplex or pay like 20 percent down and save the rest to use debt to buy a second or third property?

Considered to be the most financially free form of investing one can do in their lifetime, growing your net worth exponentially, buy & hold real estate.

The problem I'm anticipating is that with my young age and short lifetime at my W-2 job, I'll have trouble getting pre-qualified for an FHA loan.

I know most auctions require 10% percent done.

We do charge a percent, and all of our pricing is on our website.
