Already stated by @Eric Yu in an excellent way.I just recently turned 30 and I can say with absolute certainty that if my light bulb moment came at 22, I would house-hack without question.

Do be warned though, other investors aren't suggesting you shy away for nothing.

Based on a video walkthrough, the property needs new paint throughout the house, new carpets in all the 3 rooms, new kitchen countertop, new light fixtures and i plan on resurfacing the popcorn ceiling. 

If you decide to put more cash into it, make sure you don't overspend as sometimes the neighborhood's average price/condition/demographics doesn't look good for a brand new gutted property with marble floors and European light fixtures.

That is when you need to replace carpeting, paint walls, replace lights or plumbing fixtures, replace doors and repair windows, etc. 

Give them your business card with phone number and tell them that if you see anything suspicious call the police and you no matter how late or early.Gray area stuff, the home isn't yours and you could be in hot water if the listing agent or seller find out that you placed a cage over the unit before you close so tread very lightly.   

Adding in a light reno will force appreciation even higher.

Hello all.I see from looking at foreclosure listings it warns that not all liens would be removed after a foreclosure sale.
