>u can get a house costing much more then 100k with a downpayment and a home loan right?

Please don't take this the wrong way, I'm not coming down on you and mean no offense: If you don't fully understand the concept of a mortgage, it's highly unlikely that you're going to make a lot of money being the landlord of a single family rental. I would read the wiki linked on sub and follow the steps pertinent to you. This will help you preserve (and grow) your inheritance while you educate yourself about real estate investing.
