There is enough driveway space to give everyone their own parking space.The catch is if my fiancé and I get the house we have to live in a beautiful place and pay 300-500 to cover the mortgage until we can move out and rent the upstairs.

I think standard lease clauses are fine, since your only option is to catch them for something other than non-payment (like waving a gun in the parking lot, if you get that lucky).I think the theory of lease non-renewal doesn't work with most judges since it only means the tenancy is now month-to-month in their legal minds, which is still a lease except they're still not paying which is not allowed for eviction/FED as a cause now.If you find something shaky to nail them on and go to court, most judges side with tenants and will look at it as a cover to evict them for non-payment. 

@Joe SplitrockGood catch!  

Prior to forming the S-corp, my husband was a 1099 contractor in the same field with the same contracts.The catch: the IRS bungled our original S-corp election and we are in the process of attempting to resolve this with them. 

The lease you have appears to be a catch all which is great.

We are building 3 to 7 million dollar houses.You won’t find people in foreclosure or people who are behind on property taxes.Mostly people will not sell at a big time discount as they are not in a rush and have other homes and other options.You have to catch people at the right time and make them a strong and competitive offer.But I look for older homes that the owner has had for decades, usually.

Cap rate does not make the property worth less, some people see high cap rate properties and think there is a catch but not always. 

It is like catching a bank thief and they say "my bad, here is your money back". 

Moreover, my understanding is the owner of the property has right up until the auction starts to reclaim her property by catching up on all payments.

Sometimes people like that aren't that bright and you can catch them in their lies.
