I plan to use this line of credit to put down 20% on a property for a DSCR loan (DTI is too high for a vacation home/investment loan), and I do have about $20,000 of reserves saved up.

It's all dependent on state and city but where I live a 60 day notice to vacate is sufficient after purchasing, especially in leases where the wording is vague and mom&pop landlords were using Word document leases.

Looking into purchasing a vacation home and i just learned about different types of financing products and I'm curious what is the different between DSCR loan v second home/vacation home loan ? 

My family and I recently relocated to Orlando where we also started a Vacation Rental Property Management company. 

(Max vacated rents - your monthly mortgage payment) = +/- net cashflow.

He may have you issue a notice to vacate or something right at the close of escrow since you have to give 30 days notice and this can possibly be a proactive way to prevent any funny business at the end of the 30 days. 

From their point of view, you are ruining someone's vacation, and can't be trusted to supply a good product (your property). 

Sorry about my vacation time being away.Are you the owner of the Series and all cells?

My biggest STR home run was purchasing a property in a vacation market before STRs were common.

Just be honest and fair and give her required notice to vacate-don’t get into all the nuances which would be problematic to getting her out anyway.
