Hi Lakisha and thanks for your post.
I am going to assume that you are referring to some auction homes on Auction.com where the request is for investors only. When you see this there are usually two reasons for the requirement:
1. The home is in a state of disrepair (or the condition cannot be verified) and a mortgage company will not provide a loan for the home AND/OR
2. The home requires a buyer who can purchase the property with cash only.
Also, more often the not, when a home's condition is questionnable or the occupant refuses to leave or allow entry into the property, the home seller (which can be the bank or a private seller or institution) would prefer a buyer who is familiar with these types of transactions and is in a position to deal with the eviction, the damages, and the renovations that will be required to make the home saleable.
Now, if you have cash and can buy the home, but want to live in the property, then you can certainly qualify as an investor. However, you should be aware that the home's condition will probably require major renovations and the seller is not providing any warranties or guarantees (implied or stated) that the home is in livable condtion. Also, you should be prepared to deal with an occupant that may not want to leave the property.
In any circumstance, you should be prepared (if you really want this property) for, at the very least, a cash purchase of the home, possible legal issues with tenants, and extensive repairs. If these are not at all daunting to you, then you can certainly consider the purchase for yourself, but there are risks, and you should be aware of these before "leaping" into the auction. Talk with an attorney and your trusted Realtor for more help!
