As I frequently say in my book, blog posts, and forum posts, cap rates are simply a measure of market sentiment.  

I think one of them would be a Subject To agreement from your brother to an LLC/partnership that you and your brother create that would allow the loan to stay in his name but the LLC would operate the property and earn the cash flow. 

If your reason is "I didn't like they way they looked" or "I didn't like their attitude", those are very subjective reasons so just be careful. 

I have not considered them in the past due to lack of experience and knowledge on the subject.

I read so much but most of the books gloss over the subject and are more of motivational books than substance.

On my 2nd career loan, I had to get past this condition because the subject property was more than 100 miles from the employer, which most would consider an unreasonable commute.

Any lease you would be able to write would be subject to your ability to close on the property. 

Frequently people screw in the wrong size fuse and that can result in the fuse not popping in an overload and that is one of the reasons breakers are a better option.  

There may not be a tax lien of record if the IRS didn't record one but if there is, I believe it would attach to the land and any subsequent owner's interest would be subject to it. 

We were asked to get a POA but that would have been subjected to the same time delay because they both needed verification sent to The States.
