This will cause people to figure out loopholes and cause rents to rise even further.

was trying to use equity on 1 of my properties to purchase more this year.dti was the cause of rejection.

IE tenant or subsequent buyer defaults causes huge damage and your now faced with negative cash flow for a year and 20k to fix the place. if you can handle that its okwhat happens though is you have unsophisticated sellers and in a lot of instances the home is lost to the bank and the sellers credit is trashed.. plus many times they want to buy something else and with this mortgage still in their name they cant.its just a very risky dangerous thing for a seller. 

It has worked pretty well so far.Online rent collections are also a good route, my major issue with them is you cannot block partial payments which could cause a problem down the road.

Also, requiring a prospective tenant to fill out an on-line application before being contacted to make an appointment might cause a lot of people to just go to the next property in their search results list. 

Damage to garage door after partying or fighting reported by other tenants and only now confirmed by seller's agent.Furthermore, one of the tenants on the 3rd floor has reported to me that tenant of second floor has made threats to physically harm her.

This issue can be avoided completely by transferring the property into a land trust.While a transfer to an LLC will cause alarms at the bank and prompt them to send you a letter, a transfer to a trust will not.

What future problems could this cause ?

Issues identified during walkthrough on 4 March 2019:3/1 unit - actually 2 bedroom, 1 bath - ‘3rd bedroom’ is actually a den. 2nd floor bedroom has sloped floor.1/1 down unit - water damage in bathroom ceiling, no bathroom sink, no bathroom light fixture, pipes recently froze1/1 up unit - low water pressure, possible water damage in living room ceiling, damage around entryway from living room into kitchenAs the property isn't of the quality we would like to live in ourselves, in addition to not wanting to ask the 10yr tenant to leave, we're looking at this as a full investment property that we would manage ourselves.  

Its close to 3 months of time and resource investments.PSA has provisions for brokerage and damage claims in case of seller default outside of Force Majeure.
