If I were you, id high ball everything , sounds like major damage to this house     maybe shoot for 60k rehab, high points on the hard money..... even if you buy cash at 30k +60k + hard money fees + closing costs ... you might be able to squeeze a 10 percent return out ..... if you have good contacts id say maybe It could work ... if you have only done this a couple times , maybe pass on this for something with a quicker turnaround time 

On the flip side of that, I actually I had a guy in a Rent-To-Own of mine put in brand new kitchen and he never ended up buying the property.

You have a couple things on there twice and it will depend on the area as to whether it is a good deal or not. 

Hello, im looking at a couple houses going up for county foreclosure auction very soon.

Although it was only a couple grand, it dropped my credit score a decent amount. 

I have also thought about buying a Multi Family Home within my college town of West Lafayette and then renting it out while I live in it for the next couple of years while I am at school and I was wondering what your opinions of this would be?

In other words you receive a 30% tax credit on the solar system as well as a 30% tax credit at the least on the roof that is under the solar system (full roof 30% depends on the advice of your CPA).Couple that with the roof now becoming a producing asset and offsetting the utility bill instead of a liability and the increase in appraised home value assuming the solar system is not leased then going solar makes a lot of sense at the same time as replacing/repairing a roof.

My initial thought is vinyl for a rental, but if I'm flipping it in a couple years, would it pay to go the hardwood route?

I will definitely work on freeing up the next couple weeks.

Just bought my first rental property a couple months ago but I have owned my primary home and worked here for 5 years.
