From what I've seen so far, things are going with multiple offers in a highly competitive market.

I buy wholesale on properties where there is little competition to drive the price up.

Everywhere else I have read mentions using an LLC and assigning the contract or doing a double close.What are the advantages and disadvantages of each?

I've definitely taken advantage of the keyword search and have been reading articles on landlording and starting in real estate.

But the advantage is that if I don't use it right away I don't pay interest in the available funds.

What exactly is the difference/advantage of filing Form 2553 with an LLC as opposed to simply setting up an S Corp?

I'm looking for my next deal and the MLS is very competitive in my area.

The good thing is that the knowledge you acquire will give you a leg up or two over your competition.

Tax Certificate owners have no advantage in the auction.

That book tells you about valuations of properties, appraisal process and the markets as well as comps.Negotiate a price, again, that book will talk about required disclosures, contracts and issues to look for to base your deal on.Say you take an option, get it signed and file it to protect yourselfGo to your buyer and sell the option to themYou might set up closing and let the real buyer do the buyer's sideYou go to closing and collect a feeBut, this may not be that is accepted locally in your area, a closer may not work with you, so now you have pie on your face because you didn't learn from the beginning.Gurus that say just jump in a deal are giving poor advice, you could muck around for months even years if you stayed at it and be dependent on others while you are used, ya think they want to teach the local competition?
