Beginner investor in salt lake county, wondering about financing

[Dakotta Lee]

Hey, Im new too the forms! 

Iv been listing to the podcasts and reading about investing for awhile, my goal is to create 6000$ in passive in come by the time in 24 years old. Iv been running the numbers, and figuring out the amounts of money i will have around the times of the year. I figured i could get my first property withen the next 2 months with a 3.5% down payment, co signing with my parents. (Iv been working construction for my dad, not realizing that without taxes being pulled out, that i have no job history) then my second deal ill be able to round up hopefully 40-60k by the end of next summer in savings, giving me 20 down for maybe a duplex or fourplex, then from that point on, getting 2 deals a year with 40-80k down. I realized that by the time i turn 24, ill be at around 4000 a month in passive income... (assuming 200 in cash flow per unit i buy) so iv just thought "ehhh spend the first 2-3 years going with my plan. Then when i have credability, partner to get more deals to reach my 6k a month goal. BUT! I just realized something while reading "Financial words you should know" I read about a 80-10-10 lown. This completely could change the speed that i will build my investment portfolio! I could be bying twice as many propertys, or twice the size, using 5-10% down, rather then 20% down! I was wondering if anyone knew how commen 80-10-10s where and how often you can use them? Every lown? Or only if your super lucky. I also had questions about my first investment, should i waste my 3.5% lown on a 200-300k lown. Or would that be a waste? And i should shoot high because the lack of upfront money needed?  Thanks guys
