Older seller's perspective: seller financing vs an estate sale

[Tyler Bond]

Hey BP!! I am trying to get into a deal right now as a newbie but need some advice/suggestions from all you experienced members, I would really appreciate it please. I am in talks with my landlords right now to buy the SFH we are currently renting from them. The husband is 85 and the wife is 81 and they have said they are willing to sell. Just yesterday though, the husband let me know that they spoke with their financial advisor and were advised to not sell their home now (due to tax implications/capital gains) but wait until one of them passes away and do an estate sell instead. This would allow them to keep their monthly cash flow and apparently give them some tax benefit. I have no idea what the tax benefits of an estate sale would be for them, but I am wondering if some sort of selling financing deal would give even better tax benefits to them as the sellers. Sounds like their concerns are keeping their monthly income and reducing their tax liabilities. Can anyone help a newbie out?
