A base closure could make your business plan obsolete.  

Does anyone have any thoughts on whether or not the content has become obsolete or remains relevant?

The OP is obsolete.

("Usury", as we like to think of it, is an obsolete concept.)For REI, savvy investors are recruiting private money (IRAs, 401(k)s, etc.) and paying 12% to 18% for short term funds which are paid back out of the proceeds of the rehab or fix-and-flip.

Section 4The US dollar will be obsolete and replaced with a trackable token.

This entire post might become obsolete one year from now.However, it's not my post I worry about.

If it were mine, I would (probably) make the interiors up-to date modern so that it is not super obsolete looking in 10 to 15 years.I would do them as they turn--one unit at a time--and spread the financial hit out over time (both the added turn time and the added out of pocket).I would also check the water heaters for age (service life) too, as well as doing any electrical upgrades when the walls are open (adding additional GFCI outlets or etc...)My rational about this is would be, can the place get market rate rent simply by painting over the paneling (which seems low end to me), and what is the close in competition offering and getting in rent?

@James Wise Interesting, I can definitely see you're passionate about wholesaling being obsolete as a method of ammassing capital in Real Estate. 

PS I've found leaving a bouquet of flowers on the bed ($6 at trader Joe's ) is one of the most mentioned highlights of my reviews.The obvious downside has everyone points out, is that you're only one vote away, whether that be HOA or city council, from being obsolete.

If you can transfer your assets before the need for long term care then the 5 year period will be obsolete and then you can use long term care as a buffer.
