Recently deceased owner

[Tabitha Fox]

There's a home in my neighborhood that I'm interested in. I noticed it hasn't had any activity around it lately and after doing some digging around, found out the lady who owned it was in her late 80's and was either in a home or moved in with a family member. I wrote a letter on April 13th inquiring about purchasing the home. Well, I haven't heard anything and when I checked the obituaries this morning, she was on there. She passed last Friday. According to the obit, her husband has passed, and she didn't have any children. She has a sister and nieces, and nephews.

So, they already have my first letter. I'm wondering if I should follow up with a condolence letter and still let them know I am interested in the home so they don't have to go through the trouble of listing it and whatnot? Is this proper etiquette? Should I leave it alone and see if they contact me?
