Submitting an offer on an MLS Property

[Steve Leonard]

Hey Yall,

I'm brand new in the Real Estate game.  I'm ready to step out of my comfort zone and make some bids on some properties.  Think I have a handle on if the property is not listed but I found a property that is listed with an agent for $190k Comps are $190-$240k range.  The owner lives in California and property is in NC but the description says to make an offer.  The property was purchased for $27k in 1972.  I'm assuming to wholesale this property I'm going to need to be around $115k then list for $125-$140k.  So a couple questions:

1. Do I just tell the listing agent my offer is $115k (cross my fingers) and to send me a contract?

2. There's really nothing to prevent the realtor to come back over top of my offer and take the property for themselves if the seller agreed to such a reduction correct?

3. When/If I get the contract from the seller do I take it to my attorney and have them adjust the language to allow me to Assign or Double close? Make sure I have a 30 Day inspection period. 

Thanks so much in advanced.
