Are there any consequences for him ignoring my written request and invalidating the 5 year warranty I had paid for that still had 2 years remaining?

Are there any consequences I should be aware of?

It can be in appreciation, in trading up in assets, etc.With 50k, it really depends.

Unless you can do that I would start paying off my 401k debt and learn to raise private capital. expansion is good, but you are trading a lot of net worth for cash flow. learn to leverage outside capital so you're adding to equities rather than shuffling them.

Also, I have no experience in trades or homebuilding, both of which (in hindsight) would have been nice to work on.Any general or anecdotal advice would be much appreciated.

The problem is that the majority do exactly that, but a great professional real estate agent knows what boxes to check and the tricks of the trade.

If you have U.S. credit, 2 scores must show with at least 2 years of trade line history.

Its a trade off. 

However, for commercial properties in Colorado Springs it is common to see deals trade at a 5% cap rate.

The nonsense that DSCR loans do not matter if they are not on a credit report and the advice above has real consequences on borrowers ability to accomplish their goals for investment but also ability to buy their next primary.
