House Hacking: How Do I Do My Next Deal?

[Jacob Fail]

I recently purchased a duplex with a SFH on the property. (Triplex) We purchased for $195,000 with $189,000 financed with 3.5% down @ 3.25% rate on 30 year fixed FHA mortgage., it appraised for $200,000. So I have some equity and raised the rents to $800 each. So we live for free in the SFH and cashflow around $200-400 a month and another $20-50/m from the coin operated laundry onsite. My question is how do I do this again and purchase another 3 or 4 plex without having to put 20-25% down. I know seller financing and subject-to are ways but can be risky. Is there any other way that I am able to build my portfolio without having to put down a ton of money for a down payment. I am a new investor and want to grow my portfolio quickly.
