wholesaling advice needed

[Quinton Garner]

hey everyone my names Quinton G out of Las Vegas, NV im new to wholesaling and I had a few questions which I hoped youd all could help me be able to answer and help me with I have some people who want to sell and work with me but I have them on hold till I can get these questions answered so please anyone and everyone id love some help.

1. when wholesaling a home I first put it under contract to look like im buying the home, then find a buyer within 30 days and assign the buyer my contract for profit. now does the seller know im doing this or do I hide what im doing?
2. when taking bank owned homes how do you get them under contract and assign them to a buyer if the bank has a no assignment clause.

l3. how do I assure how much profit I make, is it the difference in price for the sellers offer and the buyers or is it what I agree upon.

4. when closing the deal, I will not be purchaseing anything correct? I will just be handing my contract off to the buyer and walking away with a nice check?

5. are taxes for wholesaling filled quarterly or yearly and how much is claimed?

6. do I pay for apprasals?

7. lastly is it possible to put a back out clause in a contract just in case I can not find a buyer in the 30 days? I want to make sure I don't end up legally having to buy the home cause the contracts states so.

please everyone all the answers the better.
