It's 15 min walk to the angle lake light rail station. Its also next to angle lake park/angle lake which is pretty nice. The park is the only public access to the lake. I've heard there is no other way to access the lake besides those who live on the lakefront.
You've got two good rent comps VERY CLOSE to your subject property. the hanover apts, and landing at angle lake. About $1250 for 1bd and $1500 for 2bd is the going rate at this time but depends on finishes used for the renovation.
You should talk to more people about the neighbhorhoods in Seattle. SeaTac is like the armpit of Seattle. When I show houses in the 250k range (very low range), we're most likely going to SeaTac. There is no where else close to Seattle where you can buy a house that cheap except for the skyway area where you'll find some 2bd/3bd homes for 300k.
Another thought to add - do your due diligence and check for new building permits in the area. The angle lake light rail station is one of the newer stations so I'd be curious if the station will bring in lots of developer $. Think transit-oriented development.
