@Cameron Riley this is definitely a frustrating position to be in as an investor, but I really don't recommend going that route:1) They are not trespassing2) Threats rarely get you the desired results and usually just incite the tenants to leave your property in especially poor condition when they do eventually move3) It's especially counterproductive to threaten a tenant with something that is factually inaccurate, such as calling a holdover tenancy "trespassing" and mistaking it for a police/criminal matter4) You should contact an experienced eviction attorney to understand your options and the likely timeline and cost of this process5) Some people will tell you to offer cash for keys, I generally think this is a poor option and rewards bad behavior6) I recommend checking out property management options in your area so that next time the matter can be handled effectively and efficiently within the parameters of the relevant law and regulations and without the emotional investment that leads to wanting to make threatsGood luck!

The quote you mentioned leads me to believe this is a non-owner occupied loan, because owner occupied loans can have no more than 3% origination and discount points in cost, otherwise its considered a High Cost Mortgage and is not allowed the safe harbor protections as per the regulations. 

Regulations, taxes, and a government that increasingly views Landlords as evil is a disaster waiting to happen.

Pulling from general Personal Finance wisdom and lending regulations, it is a good idea to have 6+ months of operating expenses in reserves.

They will be familiar with all of the local laws and regulations and will help you evict this person properly. 

For example, violating noise clause in Rules in Regulations which is part of the lease.

In addition, check the STR regulations, tourism data (most tourist destinations will have a department of tourism you can contact, or check the tourist numbers for the major attractions in the area if you can’t get ahold of true tourism numbers).Check the hotel presence.

Or do a 30 year...14K to do buydown to around 1.375% and around 4K for closing costs (can only reduce 30 year rate by 1.75% due to Dodd Frank regulations blah blah blah). 

My requirements were credit score of 620, must have combined income of 3X rent, no smoking or vaping anywhere on the property and, a small dog over 2 years old and under 20 pounds would be considered with additional rent.
