In retrospect, should have done it like @Kevin Grove.

In retrospect, $20,000 was still too much for the property, but lesson learned!

In retrospect, that should've been a huge indication of the direction the company was being run .. and should've run myself. 

In retrospect, you should've negotiated the price before having the contractor start work.Before starting construction, try to get two or three contractors to look at the work and the design.

What I didn't think about was whether it added dollars to my rental rate and in retrospect found that it was mainly just eating up my investment reserves. 

In retrospect, I wish I started sooner.

In retrospect I wish I would of read a few books, talked to a couple educated individuals, and invested on my own.

If that were to happen, then in retrospect you will be a sad panda that you bought down the rate. 

-After acquiring the lot, I quickly realized a few things: #1 I probably overpaid on the lot a bit or paid close to market value, it retrospect I could have probably negotiated $65k on it. #2 This was a very, very narrow lot and given the building setbacks, it would be very difficult to accommodate a sizable home on it. #3 Without any construction background, hiring the right builder to co-venture on this project with me would be critical.

Also tax-wise, In retrospect, I could have considered a REIT or a ROBS but I do not know how I can do that retroactively.
