Curious about the things i cant see on airDNA, and more about how any regulations and state/county specific costs have affected yall before i dive into a purchase there?! 

Is there a rough and dirty rule for sharing wells and using a common septic for multiple dwellings to ease up on costs and make things for efficient?

According to my estimates and the fact that only minor cosmetic upgrades are required, the all in cost is 30k.

Doesn't matter what it costs it is YOUR RESPONSIBILITY.

I am curious if running ads is an economical / effective method to sell our properties faster.

That you wisely build in the costs for replacement linens and towels (also offer black face towels), possibly don't use high-end top-down shades in the Bunk Room (although those black out shades match all the shades in the rest of the house and it's a high-end property), chalk can be brushed, semi-gloss on walls for easier clean-up... and yes, there are clear check-out directions to run the dishwasher provided via an online guest book, a physical guest book, and an email I send regarding check-out the day before they check-out.

Other benefit on paying extra on one only  is that if/when interest rates drop then better to refinance one mortgage (with higher loan amount) to save cost over two refinances. 

What’s the best way to remodel this that will be the most cost effective?

But I know that finding the balance on the pro forma between the cost of the land/construction and the density of the development (which drives rents/income/cash flow) is always the challenge.

My travel is measured by cost per mile used to travel to and from the property.
