No real weight to either. 

Do the math: 100 car train, each car 100,000 pounds gross weight each.

I am focusing instead on how paying down more principal can increase my equity.What am I not considering or putting too little/too much weight on?

Just a quick clarification for all that put the weight in their feed back as the "EDUCATION". 

I guess the owner would have to weight the cost vs benefit.

Can I cut the glass, etc. in place to remove the majority of the weight, and then I'll just have the frame to remove? 

You'll want to understand what kind or notices and documents you need to get executed to either up their rent or turn the unit.Solid long term tenants are worth their weight in gold in my book so if theres a way to up the rent and keep them happy I's say thats the best route personally.

Does this guidance carry any weight? 

My realtor is worth his weight in gold and works very hard when I have a deal going with him.
