It sure seems like it is. Take for example, my client who bought in Little Tokyo in 2012. They were told by everyone they knew that they were crazy to buy when the market was still in the dumps. What they found out through me was that the condo they were interested in was going to be surrounding by a slew of new upscale development, so if they were investing, now was the time. Today, their condo has $220k in equity, is cashflow positive by $1200/mo, and rents out in about 2 weeks each time they put it on the market (because it's heavy on the student ratio, and students tend to leave every year, meaning the owners can charge market rental rates each time they have a new tenant since most of the properties in DTLA are NOT under rent control. Sweet investment).
Another client bought a loft in 2014, after living in a rental for 2 years and was getting sick of paying his absentee landlord increased rents every year. He wasn't thrilled that the market had gone up quite a bit when he bought his pad, but decided it was the lesser evil than continuing to pay his landlord. Today, his place has $100k in equity and he is paying himself, not a landlord.
A friend of mine from NYC just bought a DTLA investment pad in 2015, because she felt that she was only just now able to see some substantial investment in DTLA, making her confident about the area. Back in 2007 when everyone was buying like it was going extinct, she waited to see if there would be more growth in residents and necessary amenities to sustain residents, such as supermarkets and restaurants (smart girl). We low-balled and offered to pay for some piddly services such as termite, HOA docs, and Home Warranty, and she got the pad. It's now worth about $85k more than she bought it for.
It's 2016, and several buyer clients are looking for choice properties in DTLA--meaning large size, top floor, good views. Size will be a big deal in DTLA in the near future. What was once considered too small for a 1-bedroom is now considered huge. Nearly all of the new developers are chopping up the units, and the average 1-bedroom is now about 610sf, while back in 2007, the average 1-bedroom was 900sf.
When investing in DTLA, low price is always good, but you also need to look out for what will become the rare, coveted attribute in the long term because this is what will add further value.
