Snap flipping, lolz.
This is actually called "wholesaling". It's illegal in some states (ex: Ohio), looked down upon by many in the industry, seen as helpful by others and extremely difficult to do consistently in a hot real estate market.
Basic steps:
1- Yellow letter, call or knock on doors for properties that meet your criteria in your farm area.
2- Get yelled at and/or hung up on many, many times.
3- If an owner shows interest, make an offer <60% of ARV-repairs with an earnest money deposit <$500 and long inspection period. For this piece, make sure you are an amazing can-sell-ice-to-Eskimos kind of salesperson.
4- Get yelled at and/or hung up on many, many times.
5- If a contract is signed, pitch your "deal" to investors at biggerpockets/your local REIA/craigslist for (contract price + $5k-$10k)=<70% ARV-repairs.
6a- If you find a buyer, do a blind closing so the seller will not know that you are not the end buyer (very occasionally wholesalers are upfront about this). Sometimes title companies are uncomfortable about being involved since it's unethical and a legal grey area in many states. There is a legal way to do this but it involves paying closing costs twice and the wholesaler would need to be able to float the full purchase price in cash for a short period of time, which most cannot do.
6b- If you cannot find a buyer, walk away from that tiny earnest money deposit.
Rinse and repeat.
