The seller pays the commissions to both their Realtor and the buyer’s Realtor. Commissions are always negotiable, however, the usual rate is 3% to the listing agent and 3% to the buyer’s agent so a total of 6% of the purchase price. 

Unfortunately this question is based on your specific situation. But typically you can expect to pay anywhere from 3-5% of the total purchase price. If you want to avoid paying PMI (private mortgage insurance) then 20% down is typically needed. There are down payment assistance programs so please let us know if you would like more information on those!

This depends on the price point you are looking to get for your home and the comps in your area. However the items to add value to your home in an appraisal are typically flooring, kitchen and bathroom upgrades. We would love to help you specifically to offer our expertise for your specific situation.
