I would include servicing costs of the loan and licensing costs.

Cash out should be used as a 12-24 month loan so that you can buy another property and pull cash out at the next 12th or 24th month mark.At that point you take a portion to pay off or down the first loan and use the rest as a down payment on the next REI.

Quote from @Brandon Croucier: The loans are available but nobody wants to do them.There always seems to be something wrong with the properties, as lenders we just can't make enough $ for our time.9/10 Borrowers also complain about the "excessive fees" for the loan amount.If you are okay with paying 8k in closing costs then the loan is available. 

My duplex - built 1989, 2,060 sf, 2 bed/bath, 1 year old roof, value if I subdivide (county already approved) and sell each separately $150k each ($300k total)Investor duplex - built 1995, 2,300 sf, 2 bed/bath, 5 year old roof, value around $310kThe investors initial request was for an equal trade and they would pay realtor fees, which I replied wouldn't be equal due to buying/selling costs (recording fees, title insurance, closing fee, survey, inspections, loan fees, 1031 fees, accountant fees, repairs), taxes would increase due to new sale price, I'd trade a 3.75% mortgage for a higher one, and I'm on the 10th year of a 30 year loan so resetting that to a new loan would restart amortization and pay more towards interest.

Yes, you can “save” interest by paying off a loan faster - SO WHAT?  

I want to purchase an investment condo for $150,000.I want to get Heloc loan from my other investment condo for $50,000 and use it as downtown payment for this condo.Can I get a 30 year fixed conventional loan for $100,000 and use $50,000 for down payment from heloc?

@Kyle Trotman If you purchased with a hard money loan conventional lenders will require extensive seasoning to utilize the new appraised value for cash out. 

If you create or fund an IUL instead of paying cash you can then get a loan on the IUL.

FHA loans didn't contain DOS clauses until 1989, VA loans 1988.  

I have leveraged VA loans, not for this case though.
