One has a 4/2 upstairs and an ADU (2/1) in the basement, but they are not separately metered and doing so is not an option (also, yard is not divided). 

My other option would be to do a 75% LTV at 7.5% interest, but I would have to come up with $20,000 to pay off my HELOC or carry the balance on my HELOC and pay interest on that as well.

Also, think about hiring a property manager.Regarding the Florida ADU,Using a HELOC can be an option, but speak with a financial advisor to ensure it aligns with your financial goals and risk tolerance.

@Sumiya Mahmud Have you looked into some of the self managed software options?

If the asset needs updating etc you may be severely limited in carrier options until upgrades are made.

Sounds like moisture intrusion issue, both options suck.

So true, and any aggregated list of all of the various fund options will need to some serious disclaimers about investor due diligence & liability.  

For example simply filing a quit claim deed to transfer the properties to one entity (existing or new) would be easiest however that may not be an option if you have loans in place... 

Before the settlement and after this settlement, buyers always had the option to approach the listing agent directly with an offer, a power they've held all along.

Local or national groups could be a good option.
