Selling pre market

[Benjamin Haberman]

On my second flip. Have buyers willing to go under contract within next couple days before we are even finished. We came to an agreement on price and agreed any additional add ons would be added to purchase price. They've confirmed they want 3 add ons. Concrete driveway($8 k), finish garage ($10k), and a new roof ($4 k). I'm concerned of a couple things. 1. Doing all of this work before we close. Any recommendations to make this more worth it? Bigger deposit? 2.the home not appraising with all of the additions. Any thoughts? Thanks so much
