I am wondering if building log cabin is going to create more equity vs buying an existing log cabin?

Once you locate an area, dig into the average nightly rate, create a spreadsheet that calculates average occupancy (AirDNA can provide this) along with average nightly rate and begin plugging in properties & expenses in your target area to see if these align with your goals.

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23DSCR lenders generally let you vest either individually or as an LLC.

Many small engineering contracts include dealing with comments from the applicable jurisdictions. 

Cost will include purchase price + Rehab cost. 

They agreed, including them paying all closing costs, and we had set a price in the lower 400ks… I asked for more money, which they obliged to add about 10k to, but just today they said their partner pulled out.

That doesn't include your time and expense to get he property re-rented.

The longer the term, the less of an impact on the rate.I've included an example below to help illustrate this. 

This is more a B- class neighborhood.I plan on doing a remodel of the kitchen including new countertops, range and hood, refrigerator, microwave, dishwasher; the cabinets are actually in solid shape and hardwood so I would like to keep them, but they definitely need to be stained and will also be adding hardware on them.
