Depending on how everything is set up, what you consider a max for retirement account contributions may only be the 20k limit whereas you can go up to ~$70k in total with other methods.

I have been looking for a retired kitchen space to cut down the costs.

Where little Tim and Jenny can get a good education, the family can live in a modest house, and still have enough left over to save for retirement?  

The home is about 1 block to the beach...About 300 people, most of which have lived there their entire lives and  are retired, still believe it still is an old PG&E plant that went off line many years back. 

Most of my wealth is in retirement savings, a taxable investment account, and my house.

There's a few other things to think about too: 1 - Possible owner financing if he wants to still get a stream of income into retirement at an attractive rate compared to the rest of the market (win/win scenario, you don't need to come up with as much cash, and he makes a little $ on the %) 2 - Consider a post possession if he needs some time to move out but needs the cash up front for whatever reason 3 - Leave all the furniture/junk in the property and you'll handle clean up etc. 

Condo Karen is much worse than some former builder retired into a code enforcement role.

This is a great way to grow your RE portfolio and Start building the cash flow you want for retirement. 

These people are clearly the victim of some brilliant guru who told them how to retire early/escape the rat race/be their own boss/etc, but forgot to mention the part about it being really tough, and like 95% of people (rough estimate just from my brief experience here on BP) fail.
