It's not great either but they are stating if given this deal once I have 5 properties; they will allow me to convert my 5 properties (I have an LLC but the properties are all in my name not in the LLC yet) over to a commercial loan (5 properties min) and give me a line of credit to continue buying additional properties.

Permitting for additional bedrooms and garage conversions requires compliance with zoning and building codes.

In terms of Costs associated with an LLC-Roughly like $100 to file with the secretary of state in Ohio if you wanted to do it yourself-Cost for your accountant to prep a tax return at the end of the year for that LLC (depends on your accountant)-Cost of a higher interest rate with a DSCR loan -Maybe more advanced, but if you have more rentals the cost of additional bookkeeping software like having to pay for additional quick books accounts.

I'm bringing on my friend as a consultant to further our knowledge base and create some additional comfortability with the financial investors.

I wasn't sure if I needed to add in anything additional from a legalese perspective. 

Additionally, I’ve been wondering if it might be possible to create an LLC, rent my house to the LLC through a formal contract, and then have the LLC operate the Airbnb.

Additionally, you may be asked to show some availability of liquid cash/assets to weather a storm in case something unplanned happens. 

I'm concerned that the combined load of heat pumps and ancillary heat strips, along with other appliances, might exceed the 100-amp capacity during winter.As part of our future plans to add a third unit and separate the utilities, we intend to install two additional meters: one for common areas and one for the new unit.

These are professionals with additional training and a stricter code of ethics.

Any additional permits?
