With demand for affordable housing in Washington D.C. on the rise, investors have shown interest in breaking into the Low Income Housing Tax Credit (LIHTC) market in the D.C. area.  That is according to Linda Rangel and Michael C. Polentz of Manatt, Phelps & Phillips LLP. In the exclusive commentary below, Polentz, who is co-chair of the real estate and land use practice group in the Palo Alto, CA, office, along with Rangel, an associate in the group’s Orange County office, say that due to D.C.’s Tenant Opportunity to Purchase Act (TOPA), doing so has not been easy.
