I'd just worry about what numbers work for you and present an offer that reflects that.

It is not reflective of reality. 

The listing price reflects an expert's opinion of market value That's just not true… First of all, they don’t even know the market value most of the time.

If you will be living there, you should adjust your monthly gross income to reflect that. 

I personally don't take votes into consideration much as they aren't a true reflection of your contributions.You can post incredibly valuable content to help other members and they still may not vote for your post.This doesn't make your post/insight/information any less useful it just means they didn't click the little button.There are plenty of people like myself with higher posts than votes because we interact a lot with others on BP.I can't expect to get a vote every single time I reply to a conversation I'm having with someone in a thread.

Broker/my mentor is suggesting to be realistic, and present a price that reflects what the new buyers' expenses would be.Is it more of a standard practice to calculate the price based on current owner's expenses, or future owner's expenses?

Reflecting, we’re very thankful for the learning experience (and work to never be in that position again).My wife and I purchased our first home back in 2004 just before the bubble in Avalon Park, FL (suburb of Orlando).

This number is reflected as the Amount of cash needed at closing.

@Chris T. is exactly right on negotiating lower than value since you're cutting out the additional fees and sale price should reflect that.

Certainly not all deals work with high LTV, but that might be reflection of that deal or the area.
