I recently returned from a trip to San Diego to check out properties there. One of the townhouse I looked at was near a rail commuter service that was under construction. I have no way of knowing the noise level I should expect if I should by this home. I emailed the rail authority and they told me the environmental impact report said in that area the noise level could be 53 to 57 deciibels, which means nothing to me.
I did an internet search and it told me that a refrigerator is about 50 decibels and an air conditioner is about 60. The problems is both refrigerators and air conditioner very widely in the noise they make. The townhouse is about a block from the commuter line. What do you think?
you also need to understand where the grade crossings are. The FRA allows train horn to be at 110 decibels. I the house is well constructed then you can do a staggered stud costruction to create a Acoustic decoupling and then buy Milgard Quiteline series windows which has STC of about 46. If such remodelling is not an option then you can simply strip of the sheatrock and use quitrock increaisng the STC of your walls and change the windows.
How are the rents for the area? Assuming rents in a worst case scenario go down some (from noise), would you still be ahead or cash flow positive/neutral? Obviously if situation turns out to be quite fine, more gravy…
