@Kurt Kline Like a lot of people are stating above ^^, their are multiple ways to save up for your first deal. yes there are less aggressive ways to save (online savings, MMA accounts, ETF's) or more aggressive (crowd-fund platforms, private money lending, day trading). However, I think it comes down to how bad do you want to get in the REI space & what are you willing to do to, in order to make it happen.
From a practical standpoint- I'm surprised no one has suggested getting a second job. I worked 8 years in serving tables in a restaurant from high school through college. After graduation I got a job in commercial finance- but chose to keep serving tables at night for a year and half because I was motivated to save for my first real estate investment, this was an easy way to stash away an extra $1500-$2500/month just by sacrificing some nights and weekends. Also- every time I've gotten a raise, I haven't adjusted my spending habits, rather just increased my savings amount.
I like what @Logan Turner suggested- check out the crowdfunding platforms and asses your risk-tolerance, learn about secured/unsecured debt & see if there are some short term deals you could be apart of. Or teaming up with other investors who need some rehab cash (albeit more prone to risk than online savings)- this would give you first hand experience in the REI world & provide a healthy return.
Lots of fun ideas out there, just requires time, patience, & discipline- since we're practically neighbor's- feel free to pm me if you ever want to meet up and chat real estate.
