I just finished my first flip in the Tulsa area. It was a 3 bed 2.5 bath 2300 SF full remodel. My wife found it on a Craigslist listing by a wholesaler.
We already had the financing in place before we made the offer. Make sure you can act fast if you are going to make an offer or your credibility will go down the tube if you make on offer and you can't back up the financing.
I acted as the GC and the majority of the labor on the remodel. This was good and bad. I spent a ton of time working on this house which took away from my family because I was too cheap to pay someone to so something I could do myself. This also extended the time it took me to finish the job. Total turn around was 10 months.
Make sure you know your numbers VERY well before you make an offer. Make sure your ARV is spot on. I have over 20 years of experience in the construction industry and I still went over my initial budget because we decided to put high in finishes into the house as we were going. Be prepared for unexpected changes with a contingency line item in your budget.
We made a good profit on the flip, but I firmly believe that we did that when we bought the property. You can make any house beautiful with the right materials and and some elbow grease, but if you pay too much, you are setting yourself up for failure before you start.
