He notified me a few months back that he wouldn't be renewing and we have been in contact sporadically since.

My total cash to purchase the property will be $6,500 + closing.With a contract for $43,500, I don't think there's much room for a wholesale opportunity & a 30 year loan would increase my cashflow by about $40/mo but I can't seem to find one right now.The property is a 3/2, 1,000 sq. ft. the lease renews in August, month to month, at $825.

If you have purchased landlord form(s) already, you can expect to see a credit for the cost of the landlord form(s) applied to your Pro account renewal.

They are on a month to month lease which we have informed them we will not be renewing for a couple reasons, the first being that they are a complete slob and are trashing the place / from the looks of it are the reason the place had bedbugs with the previous owner , the second being that they have dogs that are not covered under my insurance. 

Do they usually renew ?

Can I give a 30-day notice and get her out earlier or do I have to give notice that she has until July 31, and then her lease will not be renewed? 

I have a $200k LOC at 5% which is renewable each year. 

If they catch you, they will drop you like a hot potato.You can rent to someone for a fixed term of 6+ months and then renew or extend on a month-to-month basis.

It's best when starting out to keep it simple and have one LLC as you're accumulating your first few properties as they can get costly to renew each year ($200 in NC) @John Warren

I would assume that I could not renew when the lease is up next year based on income requirements, but I am not sure of the normal terms that go along with section 8.Well, with all that, I appreciate any and all advice, feedback, questions, etc.
