Hardwood vs Tile vs Lifeproof

[Tyler Boykin]

So flipping an 1800 sqft house and trying to decide on floors. I over budgeted on this one because i wasnt really sure what it would cost.

I have a lumber liquidators near me that sells a white oak plank for $1.19 sqft (i bought 2 bundles to check it out, and about 20% is trash). The glue seems to be the expensive part im struggling to find anything thats not going to run me $2000 for the whole house. (Unsure on sealer/varnish as of now) with me and qn assistant i can probably do it alone in 5-7 days.

Tile i have found good enough stuff at $1.50sqft and then the thin set would run around $700 for the house. And grout $500. Probably 7-10 days with 2 assistants.

Life proof comes with a mosture bearier and is $2.99 a sqft super easy install probably 2-3 days alone.

I have no idea which will raise the property value the best. At first i thought wood in rooms tile everywhere else. Some houses here have wood everywhere but bathrooms. Ive never done the lifeproof stuff but i keep being told its the way to go but im afraid people think its just cheap crap. 

what do you all put in your remodels?
