Agreed with you DR. I think it is foolish to park hard cash in RE right now.
I would definitely take advantage of a mortgage for many reasons. Inflation protection as well as leverage. If you anticipate much higher interest rates in the future, why not keep cash available to purchase high yield bonds that will be available when rates go up, rather then have that cash tied up in a home. Imagine having a mortgage, or several mortgages if you are an investor at say 3 or 3.5%, and you then having several hundreds of thousands of dollars available to lock into double digit yielding bonds. (check out bond yields in the early 80s).
You would do very well. Seems like a better way to go rather then putting all your cash into a home. I guess it just depends on your outlook.
