Home prices are forecast to rise in much of the country next year, according to Ralph McLaughlin, chief economist at Trulia.  Housing market appreciation will improve in the middle of the country, and supply constraints will also ease somewhat. McLaughlin says President-elect Trump's plans to reform Dodd-Frank and potentially privatize Fannie Mae (FNMA)  and Freddie Mac (FMCC)  could make it easier to get mortgages. But McLaughlin says Trump shouldn't just focus on the demand side of housing.  With housing inventory in short supply, he believes the real estate mogul should look to push new building projects through, in order to increase that supply.
