We live in CT. My parents own (no mortgage) a too big, old home worth app$300,000, (original cost $26,000 in 1967). They have an income, including SS, of about $2,500 per month. Parents are both in their 80's with failing health/mobility. My husband and I want to build an in-law suite in my home, which we also fully own. My parents will pay for it completely with money from the sale of their home, hopefully with about $150,000 to "bank". We intend to provide in-home care up to the last possible point of both their lives. What should be "their" and "our" biggest financial consideration concerning protecting our estates/ensuring both parties have enough money to do this as long as possible. PS -have researched a bit and awaiting our appt with elder lawyer/want to be somewhat prepared.
