I've looked at similar properties that are for sale or already have been sold but the numbers are so vastly different I'm not sure how to determine how much I could sell for. 

This appraiser was from Ohio, which has a vastly different rental market than here.

I’ve flipped in the dc area for years, right now there is just money & in the vast majority of cases there is high likelihood of losing money, right now the best investments in the area imo are buy & hold, I’ve even gone full circle and while I really liked value add for most of the last decade I think in a lot of ways new construction especially in more affordable markets (I’m personally a big fan of the eastern shore market) is a much better way to make money long term than flipping and brrring while I know they are sexy & certainly you getting a huge paycheck is great, there just isn’t any money in it right now, especially in nova.  

It is nearly useless if applied to vastly different RE. 

This is the power of trusts and why trust are so strong and vastly used.

I have 20 years of real estate experience but not on the investing side, which I'm learning is vastly different.

Houston is big and one sub-market may be vastly different from another.

The vast majority of them make more money after hiring me than they made while doing it on their own.But there are always exceptions and real estate is a forgiving investment.

About 2.5 years ago, when I decided to get into RE investing, I had no experience and I turned to BP for the vast majority of my learning (thanks BP!).

The difference is vast.
