They make removable glass panel units with a dog door built in.

Hello All,I am in the process of buying a 2 flat in Brighton Park on the same block i grew up on.

PLUS Roof  electric panel  plumbing and probably waste line to the street ( big money)especially if your going to sell.. new buyer gets home inspection and well think about when you purchased you wanted all those items fixed..

What is a typical finders fee (%, flat, profit, etc.)?  

You also may want to include expenses for a dumpster, landscaping and snow removal (if applicable given your weather).Growth assumptions are likely skewing the numbers as well as you have expenses and appreciation as flat with income increasing 5% annually. 

being a west coast flyer we look out for big rocks.. out there in flat land country I was dogging radio towers 2 and 3k feet in the air  … different experience.. of course we are used to cruising much higher than a lot of the guys I talk to that fly GA out east.. 

If it's a low $ value deal it's unlikely you'll be able to negotiate enough into the deal to cover the work.A flat water/sewer fee may be acceptable in your market.

Enclose the garage or add space, and then add an ADU in the far back (granny flat).

Here are the items that bit us:Retaining wall, which we built ourselves, even doing it ourselves it still cost us $2,500.Replacing old fuse panel with modern breaker box - $3,000.

The other way is to agree on a flat fee.
