The unit numbers in red are the ones that have sold. The smaller units facing the railroad and over the loading dock are selling rather well. These units are generally 1 BR (600+ sqft) in the $300,000s and 2BR (900+ sqft) in the $400,000s. The units that are larger, quieter, or have better views are in the $600,000s and $800,000s and are not really moving.
My theory here is that small money is dumb. There are a lot of people who can qualify for a $300,000 or $400,000 loan and are desperate to buy something, anything, for whatever reason. Let's run the numbers.
Assume 1-BR at $350,000 with 20% down. Your loan is $280,000 at 4.75%. That will run you $1460 a month in mortgage alone. Your property taxes are $350 a month. HOA dues of $400 - $450, so assume $400 for the smallest units. That gets you to $2210 per month for a small one bedroom on the railroad tracks! You can rent closer to the beach for $1265.
