I generally love making better technology for real estate investors...Do you have any type of MVP or deck to review? 

One minor exception to the comment: not advisable to lose Section 8 funding which could result both an immediate lose of further rents and/or a squatting/eviction scenario.Next:1) In terms of the late rent payment(s) - consider a 3-Day Notice to "Cure or Quit". 2) If step 1) ineffective, consider the lease type - in many states if month-to-month the lessor has the right to submit "30-Day Notice to Vacate" without cause. 3) If step 2) is ineffective, an Unlawful Detainer (aka Eviction) could be pursued.

@Michelle P Stafford, Any type of calculation of rent that includes a consideration of what principle they would have paid if they bought it, or corresponds to a payment amount of a loan could be considered an equitable interest in the real estate. 

@Matthew PaulAs an investor there are about 99,999 other things that would cause me to lose sleep at nIght before this type of issue.

Why type of investing are you going to focus on? 

Let me know if you want me to send you a list from the MLS about the types of properties I am referring to or if I can help in another way. 

Can anyone point me to a good guide or advise on any major differences in this type of investing? 

@Nathan Gesner Is there a specific type of collection agency that is used for renters or any agency?
