They also had a plastic moisture barrier laid down, but over the 2x4s (directly under the wood flooring.  

I worked at that job for 14 years when he discovered he had bladder cancer & took a leave of absence for his treatment, then surgery.

I was l looking into bandit signs and saw a few videos on how to go to Home Depot to buy corrogated plastic sheet and to cut them to make the signs.

Older people have illnesses and surgeries where a walker or wheel chair is needed temp or permanent. 

I am now over half way there to having the money to put down and as of this year that "something" happened to be knee surgery im paying for.  

I had the roughest year of my life this year was diagnosed with cancer was treated with chemo, wife got totalled car accident in my paid off car, had a baby during the process, I had a major neck surgery, and a major surgery in my abdomen but now it's time to get back.

Get a utility knife, hammer, shop vac, and some plastic to lay on the ground.

You should also be aware of what plasticizers were uses to make the products as that has become an issue (CNN had a big article about Home Depot's removing a certain one by the end of 2015).Finally yes there are other options but they all have their pros and cons; Ceramic has weight issues but is very durable, Wood in a rental (GOD FORBID, unless you're good at refinishing the stuff every time a tenant moves out, hiring it done is more money out of your pocket) is not something I'd recommend unless this is a high dollar real unit.

In NH, a Certified Renovator (someone with the RRP certificate like I have) can scrape lead paint if the proper procedures are being utilized (signs, plastic, HEPA vacs, shrouds for power tools, wet-scraping only in HUD properties, proper documentation, etc), and you do not have to be a licensed "deleader". 

Not to be cliché but you don't want a podiatrist doing your heart surgery.
