For me this makes more sense since I can afford to put more down and it helps that houses aren't terribly expensive in my neck of the woods.

* Some mold on wood (dark staining) in attic, inspector thought it was due to the crawl space having moisture in it before,  crawl space was recently totally redone and looks very good now.

Anyone from my neck of the woods, feel free to touch base.

And I've been researching around on the internet it looks like "wood like tile" seems very durable solution. but my contractor told me it's very pricy - 3 times more for material, 2.5 more for installation. 

I completely agree with @Roy N. - but beyond that @Arnold Oh, consider the merits of investing your available cash in fewer properties to own them free and clear versus using your funds as down-payments and getting loans for the remainder to thereby obtain more properties.

If the house is 100 years old with wood heat and split shaker shingles, you need higher capital reserves. 

@Kevin Wood @Sean Xin I agree with your general comments on Houston but the downstream statements are a bit oversimplified.

Newer construction (2012 I think), quartz counters, laminate wood floors etc.

You're in my neck of the woods! 

Is the timber hardwood (oak, hickory, etc) or soft wood (pine)?
