This is about paperwork related to home ownership please. Where could one find a potential purchaser agreement that the seller fills out for a proposal to buy a house?

you're asking here, instead of google?

I tried the search engine method, but I couldn't tell which result related to what I was seeking. . .

Go to FedEx store or Office Max.

To find a potential purchaser agreement form, you have a few options:

1. Real Estate Agent: If you're working with a real estate agent, they typically have access to standard real estate forms and contracts. They can provide you with the necessary paperwork, including a potential purchaser agreement.

2. Real Estate Websites: Many real estate websites, such as Zillow, Redfin, or Realtor.com, offer resources for buyers and sellers. Some of these websites provide templates for real estate forms, including potential purchaser agreements. You can search for these forms in the "Resources" or "Forms" section of their websites.

3. Local Real Estate Associations: Local real estate associations or boards often make real estate forms available for purchase or download on their websites. You can check the website of your local association to see if they have a potential purchaser agreement form available.

4. Legal Document Providers: Online legal document providers, such as LegalZoom or Rocket Lawyer, offer real estate forms and contracts for sale or as part of a subscription service. You can search for the specific form you need, such as a potential purchaser agreement, on these platforms.

When obtaining any legal document, it's important to ensure that it complies with the laws and regulations of your specific jurisdiction. Additionally, involving a real estate attorney in the process can provide further guidance and peace of mind.
