Be ready for when everything can go wrong (tenants destroying properties, not paying rent, simultaneous vacancies, etc.) and rethink and readjust your reserves for when it does happen, because it will.

Another way to look at it instead of just increase rents but rather decrease expense simultaneously. 

My goal is to start with multifamily properties, hold the properties, refi, and continue the cycle to then or simultaneously grow into other real estate investment opportunities. 

In my market (San Antonio) you could actually flip 2 houses simultaneously (depending on your ARV range, I'm thinking less than $350K) with $100K if you're utilizing hard money. 

Your network is your net worth, so make it your goal to do your homework and simultaneously meet as many people as you can!

Also its a bit suspect that two tenants would do the same thing simultaneously unless they are related somehow.  

That's basically how a "simultaneous transfer" is done.

Simultaneous closings are legal here in Oregon but you will need to have a good Title Company that is will to do that.

Yes, I work at a direct lender here in Southern California, and we can accommodate a simultaneous HELOC with our first lien mortgage on an investment property.

You just take out a new loan which simultaneously pays off and extinguishes your existing loan.
