Can you dramatically decrease your expenses and increase your income to come up with that kind of money?

I have seen numerous times where a seller just gets fed up and accepts a dramatically lower offer. 

I guess, I am answering my own questions somehow but what I was trying to figure out is whether refinancing from 15 to 30 years is a good strategy or not with 2 main points to consider: 1) Getting 30 years mortgage will dramatically lower my mortgage (say by 40% of current monthly payment).

Year after year the deciding variables can change dramatically, for better or for worse, and give you a totally new number for year two or three and so on.Even though that is a valid point, I personally tend to use COC as a part of an larger rubric for qualifying a property.

However, my experience in these neighborhoods prevents me from making to many dramatic improvements now.

I believe Curtis was referring to a site like this: www.huduser.org/datasets/metro.htmlI found that rents vary quite dramatically within some MSA (specifically the Raleigh-Cary MSA) even when holding property characteristics (sq.ft., bedroom count, property age, etc.) constant.

An architect that I recently sold something to on craigslist spoke to me about it just out of curiosity and said that due to location adjacent to the freeway and close to bart, it would likely qualify for some sort of transit oriented density bonus, possibly allowing me to build even more units (though logistically I'm not sure how I would add more than a single unit without dramatically altering the structure of the building by raising it or something similar). 

in my 45 years of investing experience, I have noticed that more dramatic growth areas those that offer higher probabilities of significant appreciation comes at a cost in terms of reduced cash flow.

I started doing that in 2011 and I saw my maintenance and vacancy go down dramatically. 

Who the heck wants to lend additional money at something tied to 0%, when the 30YF first position stuff is spiking dramatically?
