They're also expecting an official offer on the second property soon.If everything goes smoothly I'm obviously glad that my money isn't gone, but I don't think that excuses the lack of communication and inability to respond to LPs.

What did I miss or maybe have a lack of understanding on that I should research more?

I am a Realtor in Madison, WI and so far as stated earlier, other than an offer of compensation no longer being listed in the MLS, not a lot has changed as far as sellers typically being agreeable to pay buyers agents at closing a buyer agency commission, and sellers just viewing that as a closing cost and focus on reaching a net proceed number they are happy with (if competing, one buyer may ask you to pay their buyer agent fee, but at a higher price where you could still net more than a lower priced Offer). 

They're coordinating with other agencies, collecting supplies (they have a list), and flying it down on Saturday.

Your first is already risky enough since you lack experience, combine that with 100% funding and the risk is through the roof.

Within the Tahoe basin there are also coverage requirements and permitting from the Tahoe Regional Planning Agency.

I hired a contractor who was recommended to me from the agency who sold me the home. 

When it comes to all the cost and growth assumptions one thing I lack is the experience to understand what to expect... so most long term inputs are educated guesses.

Wood quality began dropping on a serious scale in the 1980s due to old-growth timber being almost completely depleted.Most wood used today is grown very fast - not only can you visibly see the difference in quality, but the newer lumber is more prone to rotting due to a lack of heartwood.

I'd prefer not to go through the eviction process, but their lack of responsiveness leaves me no choice.Thanks in advance for your help!
