Hi Sean,
How did this turn out for you? Did you guys move on this?
Let me preface with the fact I am certainly no expert on any of this.
Based on advice from our lawyer and hearing some horror stories on BP, I setup an LLC and we've always been required to do 20%, but that doesn't necessarily mean you need to bring all 20%. We had some private money help from family, but I'm not sure if that's an option for you. For our first one, it was a friend selling it and he gave us an amazing deal and I realize very few people could luck into the deal we got. He sold it to us for $59k, we did about $8k in repairs and a year later it appraised for $97k. Mortgage is $374 and rents are $1350, so we took that equity and bought our second duplex. Wash, rinse, repeat with the 2nd one (BRRRR) and we're about to settle on our 3rd in about 2 weeks.
You could try a HELOC from some of the existing properties you and your partner already have. I would try this, but we're right around 79% in our home, so I don't know that our HELOC would be for much.
Are you or your partner willing to house-hack and live in the property? If so, you could do a 203k loan. A 203k is what I used on our personal home and let me tell you, it was a MISERABLE experience, but at the time, it was our only option as I had just started a new job and had to do a 90-day "trial" as a contractor. I was fortunate, again, to have my father co-sign on most everything, but Bank of America got so granular, I had to explain a $300 deposit in my account for selling a couch on Craigslist along with every SINGLE transaction over about 3 month period. I remember spending hours looking into where a $17 deposit came from!! Yea, it was a nightmare, BUT, it got us into the house we have now and we now have around $45k in equity, so in the long run, it was a good plan.
Just throwing out ideas and perhaps you guys have already looked at these options. Best of luck.
