I'd get the ones on the less expensive end - the appraiser most likely won't know the difference and will still see it as being "modernized."

@Matthew Irish-JonesFavorite philosopher is Richard Rorty, favorite era probably mid modern (existentialism, pragmatism)I haven't read much Eastern philosophy of any era - that's really cool that you have

I think what matters most is if the bathroom is nice, modern, and user friendly then either option will work. 

In my area this situation is common was mostly caused by work done 75+ years ago before modern regulations existed.In fact I own such as house where the house behind me has their sewer connecting to my line underneath my house!

When doing research on areas that you are interested in, I would identify industries with positive growth trends, analyze market reports, industry publications, and economic forecasts, consider emerging markets and technologies. 

@Amer Swid not to fear monger, and I do agree with the other posts, but just realize that its a MUCH older standard / "technology." 

Since this is so much of a higher risk the motivation on the buyers part is usually one (or more) of the following 1- buyers credit or wORK history doesn’t qualify them for new loan2- leverage available is greater than obtainable with new financing3 - buyer has money available to pay off loan should it be called due4- buyer is “taking over” loan with an interest rate far below what is currently available for new loan. while in the past it has been very rare that a lender invoked the due on sale clause, that was because interest rates were trending lower so the lender was getting paid at least the same rate and sometimes more than they could have earned by relending the money at current market rates and the technology wasn’t available that made identification of due on sale violations easily accessible.  

Modern projectors have crystal clear pictures.

Working knowledge of modern communication (video chat, file sharing, docusign)Really nice to have:1.

. ;-)  well, 1, my tv's dont have cameras. so the most that could be done could be reviewing data of what you watch. that data is already being sold. also, if you are that worried, dont use a smart phone, the carriers watch and sell that data. oh, and dont use the internet at home, that data is collected and sold too. you can drop way down a rabbit hole regarding this. and if i remember right, there isnt a privacy law. there is a privacy act of 1974, but technology didnt exist like it does now. so dont expect those lawsuits from TV's to happen anytime soon
