So you have some great resources right off the bat, my additional Referrals would be too many :)

What would be my best route to take if we need additional finances?

Any additional input would be great.

That would be a helpful addition to your plan as you would further reduce your cost of living.Also don’t forget from that $600 you are planning on getting in cash flow you have taxes, insurance, maintenance, capex, and vacancy to consider.With two homes, you may want to keep that extra $20k as an emergency fund rather than spending it on a third property and then be left with no emergency funds.

We rehabbed the entire property and added an additional bedroom to each of the units.

Additionally, how many calls does it typically take you to successfully close a deal using this approach?

All this in addition to 6 other lease violations... 

There is only a limited provision to make additional fixed-amount payments once a year. 

The Creative Investor Meetup is designed for beginning to advanced investors who would like additional strategies when constructing deals.All aspects of real estate investing will be covered including (but not limited to) - Wholesaling, Flipping, Buy and Hold and Commercial with an emphasis on Creative Financing.
