My goal really is to go into multifamily long term rentals, but because I can't afford the down payment, I'm thinking about starting with house hacking in a Single Family home.

Can you afford to carry land until you can close on it?

Asked how things were going Etc....He said that they really wanted to get in there just real quick to measure 2 rooms for new furniture they are buying, and their Realtor told them no, just wait until the walk-through.I've bought/sold lots of houses and have never had a problem getting into a house during escrow, nor have I ever denied a buyer from getting in to measure when I was the seller.What's your opinion on this?

Work with a lender to figure out how much you can afford, what the best loan product will be for you, and what the cost-side of the transaction will look like.

I currently own two one beds, located in Carroll Gardens and Park Slope, I also own a 3 bed in South Slope that I live in.In regards to the four neighborhoods you mentioned and how they will potentially appreciate, I would say the following:PLG- I wouldn't buy a one bed unit here, as it primarily attracts families looking for relatively affordable singe family town houses, and doesn't offer much that young professionals would be attracted to.Prospect Heights- A great area full of dinning options, transportation, bars, etc. 

I want to provide affordable rentals for homeless veterans and eventually purchase and fix-up "sober homes" for veterans in crisis. 

@Ramanjeet K.If your goal is a massive primary residence first buy enough cash flowing investment properties to afford it.

If you can't afford to hold the property and ride out a downturn, then it probably doesn't make sense to do it.

Located in an outstanding submarket with a high level of demand in affordable housing, this property should maintain a high occupancy rate in the future to come.

Multiple offers are still common, especially in the more "affordable" price points.Finally, check out this chart of passenger traffic at the Austin airport.
