@Eugene Beard thanks, it feels great! I've been frugal all my life and continue to live that lifestyle to reach my goals. For example, despite living in expensive Los Angeles for 1.5 years and having jobs that did not pay much more than minimum wage, my wife and I saved about 35k (half of our gross income) while we were there. We rented a bedroom in a house, packed our lunches every day, rarely ate out for dinner, and started a side business of wedding photography to use our skills and free time to bring in money outside of our 9-5 jobs. We invested in a quad first (closed in August) using about 75% of our savings (we had a nice chunk even before saving 35k from income). That cash flows $1000 per month, so within a few months, we felt safe getting another property. Meanwhile, my business partner found a triplex to BRRRR (October), so we found a private lender (his grandmother) to cover the purchase and we split the rehab cost. In May, we will refinance and should get all of our money back out.
In December, we found a duplex, which was not hard to afford with savings from our jobs and income from the quad. My business partner was able to get a cheap condo in there too and house hacks that to have all of his expenses paid. Now, my bare minimum expenses are paid through cash flow and I rebuilt my savings a little bit before quitting my job at the end of 2017. We still live frugally because we want to keep saving money to buy more properties. We did all conventional financing as it was not hard to qualify with my job and my business partner's fairly high paying job.
