That is unless you want knocks on your door in the wee hours of the morning about clogged toilets, leaks, or if they can pay their rent late.Best to be just another joe mowing the yard for extra cash.

Those toilets are pricey, but nice.The OP probably could replace the valves underneath instead of replacing the whole toilet.

Also, they have messed up the plumbing by flushing baby wipes down the toilet.

IE: I am currently refinishing floors right now, and plan to remodel a bathroom after.

Replace easily accessible lines asap,  buried stuff as needed or if doing major remodel.

just my opinion but most every house I have ever remodeled like that the column is most likely load bearing. 

The First: Is a newly remodeled duplex walking distance from the college campus.

We got it turned on in mid-February for basic usage (toilet, faucet) while we fix up the units, and were stunned when we got a huge bill; the private water company claimed we'd used almost 116,000 gallons of water in 12 days.

I've heard others have had good luck showing the newly-remodeled unit to existing tenants, so much so that the tenants were willing to sign a new lease for a higher price to be able to live in the nicer units.
