You'll want to have 20% down whatever you do. PMI is a fucking huuuuuuuuuge waste of money. If you are in one of the 'hot' markets where prices are going up far more than inflation you might want to keep renting for a bit. But you might not. Lots of local variables in play. I know CA is wanting in on the legal weed thing, which will cause huge inventory shortages in the short term while it's still a schedule 1 substance, because banks and investment firms can't do anything directly with growers/sellers, so they use real estate to wash the funds. Sit on the place for 2-3 years, then sell and voila you can put it into the bank or stock market. This will keep the market inventory pretty low, making it a seller's market, and will jack prices way up. But that is a crash waiting to happen as well. Once it gets taken off the schedule lists (Trump or next guy will do it) the inventory will open up much bigly and prices will plummet. Rule of thumb for new house is 5x average income for the area. If it deviates too much outside that a market correction will come sooner or later.
