Inflation is constantly eroding buying power, so your initial cash flow will be the highest you will ever receive (adjusted for inflation) from that property.

No, not for the initial purchase.

Here's what you would have (assuming for the sake of this example you bought all 5 in year 1, this would obviously be different if you bought 1 per year):-Houses are now worth approximately $210K each - so assets of $1.05M-The initial principal on the mortgage of $150K per house has been paid down about $14K each - so $136K per house x 5 = $680K-Net equity of $370KLastly... you're not going to net cash flow $1000 per month on a $200K house that has a mortgage on it. 

A market and neighborhood that is more established and has higher growth should allow you to exit or refinance faster while extracting a larger percentage of your initial investment.

I'm looking for some advise on how to finance the initial renovation cost.

I ran the numbers through the calculator and it looks like it has potiental however i was hoping someone with some more experience with the brrrr strategy could bring some insight as to raising the value of this property so after about a years time (seasoning period) when we go to refinance it i could get the partners initial investment back out of the deal. 

My initial thought was to liquidate the brokerage account for the downpayment.

I am still at the initial stage.

I want to change this.My initial search was how to separate contacts in your phone.  

My initial plan is to get new leases for the tenants, background checks on all adults, get security deposits, and verify who is living in the units.
