If your sister-in-law prefers not to be directly involved, your wife could become the sole owner of the LLC, and your sister-in-law could be given a secured interest in the home after the HELOC is obtained.Additional Considerations:You mentioned owning two other properties.

The property needs to be one we are proud to own and preferably would be willing to rent out ourselves. 

1) an investor will pay the least for your house.2) An assumable loan will only help if you owe at least 8-%, preferably 90% or more if the sales price for an owner occupant who will pay the most. 3) it’s been a VERY slow winter.  

Then sell the property and start doing fix and flip or fix and rent. ( I prefer to sell this property as it 100km away from my student rentals. ) Not sure if I should renovate the lower unit to sell.

You can create boards for each property and track updates, tasks, and improvements visually.Property Management Software: Some users also leverage software like Appfolio or Buildium for more comprehensive tracking, though these can come at a cost.It really depends on your preference for simplicity versus more structured systems.

Brand preferences ?

Financing is also easier since lenders prefer predictable rental income over the fluctuations of STRs or MTRs.Short-Term Rentals (STRs) and Mid-Term Rentals (MTRs) can be lucrative but require more hands-on management.

I also have an investor putting some cash down who would prefer an inspection be done. 

@Audrey Sommer I prefer investing in my local market (Snohomish County).

Each investor would still choose their preferred properties and the corporation would liquidate enough to pay taxes.
