Start by reading the Ultimate Real Estate Investing Guide: https://www.biggerpockets.com/guides/ultimate-real-estate-investing-guide/introduction2.

A bigger house will be higher, but that is a great starting point.

And what company/bank do you think gives the best opportunity/deal all things considered?

As someone who started buying with buy and holds back in 2005 and didn’t start wholesaling until 2013 I believe wholesalers who operate in integrity and with character bring a lot of value to sellers and buyers in the market.however Having the resources to be able to close  on deals and then if we want wholesale them has been invaluable to our business. 

If you have not been to Milwaukee, YouTube is a good start.

I called the management company to ask.

Is it required to go through a title company and put them on deed?

A great way to start is by attending RE events and joining a local investors association.

I am looking to start Real Estate(primarily focused on House Hacking and SFH if it goes well) as an engineer after graduating.

Our company specializes in full-service property management & construction aside from sales as well, so we work with a lot of real estate investors.
