Feel free to shoot me some high level particulars and I can keep you anonymous. 

Exclude any units that are out of your league and focus on similar comps. 

Supplement this far simpler entity approach by ensuring you have appropriate types and levels of insurance, you operate your business in a manner in which your conduct is not considered an exclusion in your policy, you work with licensed and insured vendors, you execute contracts with indemnification clauses with these same vendors/ require additional insured status &  maintain appropriate licensing and permits.

While rates may not decrease, the significant double-digit increases should level off.

Nightly rates and estimated revenue based on all the other units in the area?

Josh, we are currently looking at SFH and MFH with 2-4 units.

dont over think this its not that complicated. important issues are.1. cost of capital2. knowing what a deal is or is not.3. good reno crew or contractor  4. good agent that will tell you straight what its worth when done and what level you should rehab to.5. a market that is actually moving napkin math works  trying to drill down to decimal points does not.

You will also need different levels of staffing to support the various strategies as you are already realizing. 

If you only have one LLC and don’t need entity tracking, you could get a lower subscription and categorize your properties as ‘customers’, then units and tenants would be sub-customers.Simple Start would allow you to invoice your tenants (if desired through QBO) and produce basic reports. 

Without electric you can not heat the unit.
