One owner could take all the money while the other owner keeps the remaining home. 

@Dav PohoteI always look at the loan constant to help me decide between loans and their terms.You can pay the 30 off in 15 years- it just gives you flexibility if there are some bad years but looking at the loan constant will help you decide if the increased interest rate is worth it.Good luck!

Unfortunately, you will have to bite the bullet and deal with current interest rates should you decide to finance.  

Hello,I am hoping to gain some advice in deciding between multiple HELOC options.

3) Utilities while vacant or lease calls for owner to pay?

How do you currently decide who pays what for the utilities?

Now its a different owner and since you don't have an insurable interest your policy may be null and void --- ask the Title company. 

Going to give the owner a call as soon  as possible!

They will sell below market and lose more money, then the new owner will jack up the rents.

If they somehow guess you are the owner though, it still doesn’t matter because you would not be the owner.
