Get a 20-30yr annuity and spread out the tax hit.We will continue to sell 1 to 2 houses per year, depending on tax implications.   

That number will give you something that can be compared to the return on a bond, CD, annuity, or whatever.

Financial advisors will usually try to sell you on retirement accounts, annuities and life insurance while you can see from the net allocation below that these categories are a very small percentage to a multi-millionaire's overall portfolio.        

In my mind I'm building an annuity to add to my overall nest egg...  

Then I would get it fixed and sell it. being a absentee landlord in AU is not like investing in an Annuity, your always going to have issues from maintenance to tenants to PM..

It will give you very simple IRR, MIRR, APOD, annuity functions, etc.Regards,Frank

Just like the new construction I build ... if there is a warranty claim year one.. its not me who warrants it its the sub who did the work.. lest they never get a job from me again.I know of One company in Utah  a turn key company working in Indy and KC that had this elaborate guarantees.. they allowed Annuity salesmen to bring them clients at the cost of 10% per deal.. and a 24 month worry free guarnetee well the company is now in major litigation and I suspect pending criminal charges.. the reality is you cannot as a rental property provider regardless of turn key or otherwise guarantee someone's out come you will do what happened to these dudes flame out and risk potential disaster

You could jump into an annuity like someone I know that is very happy to get no return. 

Insurance annuities from similarly rated companies or REITs of the same portfolio quality.
