If a home was previusly owned and lived in by a famous person, does it add much value? 

Your margin for error on a house that is valued under $100k is so tight.

To make the strategy successful, you need to find a property that can be acquired below market value.

This is like buying any other property, it is valued at whatever the market is.

The fix-up and increased value will not matter to the IRS as long as you sell within a reasonable time frame of the house passing into the estate.

However, longer-term bonds (1-5+ years) are subject to interest rate volatility:If rates rise, bond values drop, potentially leading to negative net returns.If rates fall, bonds appreciate, but gains are capped by their fixed coupon rates.While Treasuries provide stability, they offer limited upside and carry hidden risks for medium- to long-term maturities.Why Real Estate Is a Stronger Option in Today’s MarketMultifamily real estate, particularly value-add properties, presents an asymmetric risk-reward profile that Treasuries simply cannot match.

I would also like to know the purchase price and current market value.
