What's up broski! Merry Christmas! You're in a market with a lot of good guys that can help you get deals done if you can't find a buyer yourself. Assuming you found these properties in hot zip codes finding buyers shouldn't be too hard to come by but in regards to estimating repair costs Brent Daniels (he's in your market) has a pretty good video that explains how you should be calculating these costs: (Don't know if BP will allow me to post the link but if you don't see it just youtube "Brent Daniels Easy Repair Cost Estimator")
The easiest way to find out your wholesale fee would be to find out what the cash comps are for neighboring properties that are in a similar condition to the ones you'll have under contract and see what investors paid for those properties. Once you find that number subtract 10K to fit in your fee and that will be your max allowable offer. Ex: Investors bought a property in a similar condition to yours for 100K cash so you would get your property under contract for 90K and sell it to that investor for 100K or more to get your wholesale fee of 10K or more.
