I don't want to sell the house, for sentimental reasons, and I don't know how i can afford to buy her out the way home prices are rising. 

The sentiments from all of my guests has been the same: they love that the unit is different and quirky, they love the attention to detail, they love the experience I've created for them (extra amenities like robes, teas, a bath bar, fresh flowers, etc). 

But it is true that large group average sentiments, on happiness or sadness or optimism, may slow things down or speed them up, at the margins, and over time. - It may take upwards of 3 years of sustained high (or low) rates before rising rates has any measurable impact on home values.

Is this the sentiment you are getting? 

So I would not worry too much for a 90 day BRRRR project - the market has to slow down, before it can change direction.On top of the data I can also tell by the client sentiment: we have currently about 60 active buyers and they are all in agressive shopping mode.

Don't go out of your way to make the home energy efficient unless all your competition does so "Don't go out of your way to make the home energy efficient unless all your competition does so"I understand your sentiment, my thinking is this could be separation from the competition, thus a possible value add. 

So you can buy in those "down cycles" but you are not going to see a discount - but the market sentiment will be "concerned" at least and newbies will not have the apetite to invest..

@Randall Alan, Totally understand your sentiment. 

Keep family assets separate from investing...especially grandma's house where there is a lot of emotion and sentiment.

I agree with the previous sentiment.
