California voters just passed Proposition 37 with 61 percent of the vote. The measure authorizes the state to issue up to $25 billion in revenue bonds to fund a homebuying assistance program for middle income families.The program would offer loans covering up to 17 percent of a newly constructed home's purchase price, with buyers putting in at least 3 percent down.For families in Oakland and Hayward, that could matter a lot. Many first time buyers here have the income for a monthly payment but not a large down payment saved. A loan covering up to 17 percent of the price could change the math on a new construction home.There is still a lot we do not know. The details on who qualifies, when the program opens, and how to apply have not been released yet. I will share updates as they come out.What you can do now is get preapproved so you know your real number, not a guess, and keep an eye on new construction in Oakland and Hayward.Questions about buying in Oakland or Hayward? Ask me, I help families from first time buyers to seasoned buyers.How the math could workSay you are looking at a newly constructed home for $700,000. A loan covering 17 percent of the price would be $119,000, and 3 percent down would be $21,000. Those are just the numbers from the measure itself, not a promise about what any one buyer will get, but they show why buyers are paying attention. For a family that has steady income and a smaller amount saved, that kind of help can be the difference between waiting another year and getting started now.What counts as a newly constructed homeThe measure is aimed at newly constructed homes, not resales. If you have your heart set on an existing home in Oakland or Hayward, this program would not be the path for that purchase, based on what has been reported so far. If you are open to new construction, it is worth keeping on your list.What middle income means hereThe program is described as help for middle income families. The exact income limits have not been released yet, so I will not guess at a number. When the details come out, I will break down what they mean for buyers in Oakland and Hayward specifically.What to do while we waitFirst, get preapproved. Knowing your real number tells you whether a new construction home is in reach and what your monthly payment would look like. Second, start looking at new construction in Oakland and Hayward so you know what is out there and what it costs. Third, check back here. I will share updates as the details come out, and I will walk you through what they mean for your situation.Why I am watching this closelyI help families from first time buyers to seasoned buyers, and the down payment is the hurdle I hear about most. When a program like this passes, I want my buyers to hear about it early, while there is still time to get ready.If you have been waiting for help with a first home, this is the kind of news worth watching closely. It does not change anything overnight, but it could open a door that was closed before.
