If the buyer stayed in the house more than 5 years then the outside lender was a better choice. As far as the title company, it is easier for you to use them. They have all the documents, surveys, etc already done. Check with your local Realtor. I do not work Maryland.
Agents say it shows well.
Retirement communities are a hard resale, especially if they are still selling on site. Price will always make up for whatever the problem will be. There are so many factors that make a difference when selling the retirement community properties. It is a booming market but most of the people are looking to buy new. If so how long and do you ever have to move back in it prior to selling.
