The steps are the same, utilize credit cards, take out small loans, and make sure to make all your payments on time. 

I bank and collect rent payments through Baselane and it’s a great way to set the rental terms and then forget it since the system generates invoices monthly. 

And in the end didn't make me money and the loans I had on them actually prevented me from getting additional loans on other better deals.Anyway, here are the specifics:1) purchased 7/1997 @ $80k, $500 down payment, cashflow appx $150/mth as long as there were no major repairs or maintenance items, great % returns but very little $ returns.Sold 5/2016 @$67k, after about $7k rehabwas about $250/mth cash flow at time of saleOh, and it took many months to sell, therefore costing me additional holding costs with no cash flow2)  purchased 9/1998 @ $71k, Similar and same area as #1 - $500 down payment, cashflow appx $150/mth Sold 4/2016 @$72k,after about $9k rehabwas about $250/mth cash flow at time of saleand also took many months to sellFor fun, I just looked up their zillow as of today and 1 recently resold for $85kNow, today, there are a lot more resources to easily research market areas, etc, so I now do more research to find markets with more demand and growth potential. 

Get some solid numbers on what a payment would be. 

However, If you use a bank, plan on a down payment of 20%, that's $80,000 down plus about $5,000 in loan fees and $3500 in closing costs.

I have a US mailing address with a family member and a digital mailbox for business accounts.

Once the lease is signed and they collect payment, they walk away.

Each of you are putting in half of the down payment, but I'd consider agreeing to a 60/40 split of the net income in favor of them. 

Ask for a down payment that you can then take to invest elsewhere and then you will also still be receiving monthly cash flow coming in on the seller finance payments.

I received a 15k down payment and am receiving monthly payments of $1578 for so many years.
