Loan to Finance My ADU ( Not a 1st/2nd Mortgage or HELOC)

[Brandon LaRose]

Hello All, 

I'm looking to do some work on my rental property to add an attached ADU. I'm looking to finance the project long term in a way that is helps me create positive cashflow. I expect that means it needs to be 15 years or more. And I would like to stretch it out longer to improve cash flow. I already have 2 loans on the property with great interest rates that I'm not looking to replace. I expect the work to cost about $150k plus or minus $20k. I would like to finance all or most of it. Any thoughts on types of loans I could get or where to look. Most personal loans I have looked at have terms of 10 years or less. And because I'm looking for a long term finance situation, I'm not looking for a loan that is going to have a really high interest rate, with hopes of refinancing later. I want this to be acceptable long term if I keep this method of financing.

Any thoughts?
