Sorry for late response, I have been busy with renovations on a current rental.

Their entire business plan is wait a few days to come out, charge  deductible, go back to the office to order a part or two that will come in a day or two.

It's running a business NOT renting a house.  

You really shouldn’t be running your business on a stranger googling answers for you but…the google says:  Depending on the rental agreement, Georgia landlords typically must provide a 60-day notice for lease renewals or terminations, while tenants generally need to give only a 30-day notice for lease termination.Jan 18, 2024If a new lease is not signed, and the landlord continues to accept monthly rent, the terms of the original lease still apply, except the landlord is required to give sixty (60) days' notice before she can terminate the lease or change the terms, and you (the tenant) are required to give thirty (30) days' notice before leaving.So you can’t non-renew until the end of April and you can’t even increase the rent until then.

What broker would sponsor me considering I'm not intending to become a full time Realtor and give them regular business?

Its not personal, its business. 

I'm excited you are here and ready to grow your business even more! 

Lenders want your business, and you can negotiate terms, credits, and even push for a better rate.

For bigger, more complex projects, it’s better for our business to wholesale them to other investors.

They lower taxable income for federal taxes but not for FICA.However, employer contributions made by the S-Corp are not subject to FICA and count as a business expense.Make sure your W-2 correctly reports wages, deferrals, and FICA wages.
