The short answer
Yes. A cash purchase removes the lender, but it does not remove the need to verify the home, land, site work, contracts, title, installation, and inspections.
Protect the purchase
Ask for a complete written price and payment schedule. Confirm who receives each payment, what is refundable, what happens if the site cannot accept the home, and which documents you will receive at closing.
Keep the same inspection and documentation steps
Without a lender involved, make sure the site review, installation requirements, and closing paperwork still have a responsible person. Paying cash is not a reason to skip written specifications or a clear delivery and completion plan.
Verify payment instructions directly with a known contact before sending funds, especially if instructions change. Keep receipts and complete copies of the signed documents. If you need advice on title or contract terms, use the professional responsible for that part of the transaction.
Organize the payments by job
Keep the home purchase, delivery, installation, and separately hired site work on one payment list. Note who receives each payment and what work or document is associated with it. When a change is agreed, update that list rather than relying on a text message alone. This makes it easier to see what has been paid and what still needs to be completed.
