The last time I moved I did it on a really short timeline, my wife was 8 months pregnant when we found out we needed to be on the other side of the country two months later for work or there wouldn't be any work.
I was in the construction business for 15 years, which of course meant my primary residence was about halfway through a remodel and had been for years. After spending two weeks getting it buttoned up enough to put on the market I left for a 3 day househunting trip here in SC, terrified the whole time my wife was going to pop while I was gone. While I was getting on the plane to return home, having bought a house here that morning, I got a call from my wife we had an offer on our house...for $25K more than we were asking!!!
They wanted us to cover all the costs, and finish the remodel, and change a bunch of stuff, and replace the furnace, and so on, but all things considered it was a very good offer that netted us more than we were expecting and it all worked out.
Point being a lot of buyers want to roll all their costs into the mortgage rather than have to spend money up front, even buyers who would have no problem affording to do otherwise, because they'd rather carry mortgage debt than give up their liquidity or other assets or carry other debt. Just make sure your net is where you want it and adjust the deal from there, it doesn't matter who pays what, it only matters what your check is when the deal closes, and that the agreement is written in such a way that you're not going to lose if it doesn't.
