Or you live in the SF bay area, LA, or New York. My grandma wouldn't sell her house to move because the sale price would in the $700k range while she bought it in the '60s for nowhere near that. ($20k?) A new house where she was looking to move would be in the $500k range, but after capital gains tax she'd end up with a house payment again. And being a widower, she'd only be able to take $250k, not the $500k. So it was a case of selling a house for $700k, buying one for $500k, and still owing $50k due to capital gains. Under the old rules, it would've been easy and had some cash in the bank. But as it stands, she can't move unless she throws away $300k.
I said that "only the
lucky and the
wealthy really have to worry about it". Lets look at your grandma.
1) From the 1960s to 2010, the median house in America went up by approximately a factor of 11. So a person at the median who bought a house for $20k in 1960 would now have a house worth $220k. Your grandma's house is now worth $700k. That is more than triple the gain that the median person in her situation saw. She was
lucky to have lived in an area with such a large gain. That is, unless you can somehow prove that she chose that city due to the fact that she knew prices would grow at triple the rate of the rest of the country.
2) She can sell now, move to an apartment and have a cool $600k (I subtracted taxes and real estate fees) in the bank plus whatever else she has in savings / pension / stocks / etc. The average retiree has a $300k TOTAL nest egg. So, right off the bat, if she has nothing else, she has double the
wealth of the average retiree.
Even if she won't admit it, she has wealth and had luck. Thus, she needs to worry about this issue as I said above.
And, I believe the long term capital gains rate for people in lower income brackets would probably apply to your grandma. That means, for the years 2003-2007 her tax would have been 5% on the house gain and
this year 0%. Lets say her gain was $700k - $20k - $1k (fees to buy the house) - $50k (improvements she has receipts for) - $70k (costs to sell the house) = $559k. Then, from 2003-2007 she'd have to pay 5% tax on $559k - $250k. That works out to be $15,450 of tax. That is hardly a problem for someone with $600k in the bank. This year, she'd pay 0%.
So, no, she WON'T need a mortgage to move to a $500k home. And I have no idea where you came up with the idea that she'd throw away $300k.
