Use to size up the construction market in one Rio Grande Valley city (McAllen, Edinburg, Mission, Pharr, San Juan, Weslaco, Donna, Mercedes, Brownsville, Harlingen) or the whole Valley before you lend, build, buy or sell there: permits, housing units by type, sales-tax trend, months of supply, home values, input and material prices, mortgage rate, labor. Every value is dated. Example: "Is McAllen's housing market oversupplied and are building costs rising this week?"

Returns: One Valley city's (or the whole Valley's) latest permits, monthly housing permits by structure type, sales-tax receipts, housing supply, building-input and material prices, labor conditions, newest commercial projects and this morning's mortgage rate, 10-year yield and diesel price, every value dated.
