power wash outside, paint front door, update landscaping. First impressions at lasting. Ask your friends to take a look and see the negative aspects you may not...
How funny I did yellow too! What a coincidence. I have a notebook with all the manuals and warranties for everything in the house too. If I changed a faucet, I have the receipt and warranty. Also service records for all scheduled maintenance, etc. I leave a photocopy for prospective buyers so that know they are purchasing a well maintained home and the original is conveyed to the new owner. That alone has sold every house I ever put on the market.
Most often the first offer submitted will be the best received. Unless a total insult, try to work things out. Hopefully, you will get multiples. Agents and potential buyers always know if precious offers have been submitted. If they are looking at your property, obviously something went wrong. That gives them the idea they can "low ball" you bc you lost a sale and time is ticking.
Yes, putting a binder together is also a great idea. Selling a house is like selling a car. Put everything up front, be honest and do not give them one thing to doubt or very little to doubt/question. Some people just HAVE to find something to question. In that case, make them work for it!
