I have found another deal on a duplex but do not have the funds to finance it as I have just recently purchased my duplex and am pouring all my available capital into the renovation.

My experience is almost 100% on the RE equity crowdfunding space for Don's 1st catagory (platform lets anyone raise funding).

His half of the deal he is looking to sale a current rental he has and 1031 those funds into this property We’d be buying together.

A cash out refi will be limited at a 70% LTV too. 

@Jay Hinrichs I am working with limited funds, paying cash is out of the question.

It will save you money over time for sure and paying down debt is not a dumb decision.If all you have for debt is your primary mortgage, it may be a great use of extra dollars at least until you get below 80% LTV and get the PMI rip off removed.

As I read Finding and Funding Great Deals, there is so much valuable info and I realize I would like to have a Broker/Agent mentor with similar experience.

There are conventional programs that go as high 85% LTV on investment properties.

With borrowed funds there are a lot of rules to follow here is how they can trip you up. 

He has the cash funds but He wanted to use a mortgage.$500,000 Value requires $150,000 + $22,000 Closing Cost so total of $172,000 Down + %5.4 APR 5 ARM + 24 months payments needs to be in the bank account which is approx $73,000At the end of the 5 years, the mortgage will be something around $322,000 so with the appreciation etc if we sell the house around $600,000 which - $172,000 - 322,000 = $106,000 NET max return.But if we go all cash , he can make Approx $225,000 ( total rental income + average appreciation)Or If we do All Renovation + All Cash deal =$550,000 investment in 5-year approx profit will be around $300,000If you'd have the All Cash Funds and if you would locate overseas so you don't have time but you also want to make profit , what would you do in this situation?
