Most state laws say the 30 day notice starts at the beginning of a rental period -- so, on a month to month rental agreement,  if you want the unit empty by October 1st, give the notice by August 31st.  

I've finally gotten myself in a position to where I have enough equity to comfortably purchase my first rental. so now, I'm going to start getting more involved and try to learn quickly. 

This will have a noticeable impact on home owners.  

As a general rule this is usually a 30 day written notice and two months worth of rent by the tenant to "legally" break their lease. 

Since 20 days notice is required, the next foreclosure date will be the first Tuesday of the month following the expiration of 20 days (foreclosures in Texas are all carried out the first Tuesday of every month).The trustee will charge for this service, which includes notification, by both regular and certified mail to the borrower, filing of notice of intent to foreclose with the County, and holding the trustee sale (auction) on the prescribed date.

My ultimate goal is to acquire enough rental properties that will produce enough positive cash flow so my family will be financially free.I'm looking forward to learning and networking with everyone here. 

In general, I'd just posit that "deal source" should not be conflated with "deal quality".

The property is currently being rented for $2,400 with an immediate positive cash flow of $1,000.

Monthly mortgage payment for 30 years with 4.5% interest rate is about $1,400 (total monthly).The property is currently being rented for $2,400 with an immediate positive cash flow of $1,000.

In this case it sullies (in my opinion) their reputation, is a huge waste of time, and might implicitly validate a strategy that won't yield a positive result.
