I am working on a product that will help small-medium size landlords launch and maintain Internet presence at a small monthly cost without spending big budget on custom development.It will include: SEO, custom domain, direct syncing with your property management software, syncing with QB. 

Their customer service was not helpful.

Yes, bad time of year to rent, but making exceptions to rent quickly may not be in your best interest.

Once you pay it off, it goes back to normal relatively quickly (within 1.5 months).

This is fine when values and demand are rising, and things are selling quickly.

I also don't think they are customers. 

An activity is a rental activity if tangible property (real or personal) is used by customers or held for use by customers, and the gross income (or expected gross income) from the activity represents amounts paid (or to be paid) mainly for the use of the property.

By reducing your tax burden of your W2 while also reaping the benefit of the short term rental cash flow, you may be able to free up more capital to scale more quickly.

I want two things - I want help customizing a lease for my property.

Customer service has also been very good in my experience although hold times average around 5-10 minutes depending upon the time of day you call.
