I've done this myself more than once.You will want an architect (figure a few thousand for plans).

Our plan is to start our business/investment there.

Planning a flip of the property with 50k cash buyout + 40k estimate of renovations.We've considered paying cash for property, obtaining loan for 90k-100k and paying ourselves back first before starting renovations. 

Plan on 25-30% down. 

My plan involves paying off the first mortgage's judgment amount afterward.

We are planning to turn our primary residence into an STR at the end of this year and are looking to take advantage of accelerated depreciation if we can meet the REPS requirements.

You won't get the replacement cost if you plan to walk away.  

My outstanding loan balance is 163K @ 3.5%I calculated that I'd clear 900/mo after expenses.I was planning to buy my new house for cash, but with the market where I'm moving/buying I'm having to go about 100K over what I was planning, so I'm taking out a 50K loan for that property.

Many resorts hire seasonal staff that needs housing.All said, if you can acquire well, and your plan is appreciation, Tahoe is an awesome place where real estate is a limited resource.Consider snow removal.
