Advice needed: Sell stock or find a partner? GO!

[Justin Mathews]

So here is the scenario: I have a deal under contract for 3 duplexes in a row that are turnkey and already flipped. They will cashflow $4900 a month and net around $1800 a month after all expenses, capx, etc. It will require $70,000 down to close on a 15 year 4.1% loan fixed. I like the debt structure and timeframe for the loan. I like the cashflow as it will give me about a 29% cash on cash return in the first year. This is way better than the stock market. The 6 units are already rented with fresh 1 year leases as well that I have vetted and like.

My question is whether I should reallocate my limited resources by selling some positions in the market to fund the 70k or seek a loan partner for the down stroke? 

I do not have cash to burn so this is a significant reallocation decision. There is enough cashflow to share with a partner but why do that when I don't have to this time? Next time I will need to partner to get the downstroke or just wait and save until I have it to buy another property.

Advice? Go! ...
