3 1/2 years before my mother died, she sold the place where I grew up and moved into an apartment near my sister, and financed the sale (to someone she knew and trusted; her hairdresser). The new owners sent her a check each month. No 'escrowy thing.'
After she died, I (her executor) sent a letter to the owners and asked them to start making the check out to 'the estate,' and send to me. I held the funds in a separate estate account until we settled the estate, and then disbursed the accumulated funds to my brother and sister and self. Then my brother and sister and I formed a simple partnership, with me as the managing partner. I sent the owners a new letter asking them to begin making their checks out to 'the partnership,' and I disbursed a third each to my siblings and kept my third each month. Again, no 'escrowy thing.'
Each year I prepared a simple K-1 to report the interest, and sent to IRS and brother and sister, and kept a copy for myself. When you file your taxes you have to report the total received, which includes the CG. But then there is another line later where you subtract the CG out, so you only pay tax on the interest.
It was all pretty simple. Maybe yours is more complicated if the house is already in a trust. Good luck.
