Anderson does have a pretty vibrant sales force, so they can make you feel like you are not being wise by not buying a LOT or All of their services (which typicalls is $10-$15K). 

@Brian Eastman is correct and I will add that outside of being 59.5 there are some (though super rare) employer plans will allow you to roll over some or all of the funds in your 401k. 

Most of the best companies have reps (some better than others) in some states or all 50 like we do.

It rarely makes financial sense to sell before completion as you lose most or all of your previous efforts so completing it should be your goal unless you will be putting in more to lose more in which case, cut your losses now.Borrowing from friend/family, borrow from private investor, line of credit, HELOC, sell any asset you have, credit cards, terms with suppliers and service providers to be paid once it sells, etc. can all be means to get you to completion.

FHA You always find a due on sale clause in the mortgage when you consider doing some kind of taking over payments like subject to for wrapping existing financing in a wraparound mortgage or all-inclusive trust deedWhen Selling: avoid wrap-aitd, sub2, land contracts; do a lease with rofr and help the buyer get bank financing (search lease + rofr is better than a lease + option on BP)When buying: best is sub2, then wrap, then cfd-lc, then lease w option.I always say, exit with a month to month lease on sub2 or a fix and flip with a sub2; NEVER wrap a sub2 purchase.

I'd live in one apartment, and rent out the others, one or all of which might be medium term furnished rentals.

If I gave some or all of my house to my son before Prop 19 became effective he might dodge the property tax increase upon my death BUT he would inherit my tax basis for capital gains taxes when he sells after or before my death.
