I try to be compassionate and listen.  

Be compassionate as you do it but move her out and put someone in who can pay.

The long term impact includes the following:-Less compassionate landlords who are willing to be flexible with late payments, evictions, or delayed move outs-Less supply of rental property due to single family rentals being liquidated and sold to buyer/owner occupiers -More competition from bigger REIT's (real estate investment trusts) and real estate holding corporations who can weather limited returns-Less incentive for real estate developers to rehab and hold properties long term in the local area-Less flexibility to keep rents affordable without falling behind and keeping up with market rents to appraise at exit -Less business in the investment property sector due to lack of supply, including realtor commissions, title and escrow fees, handymen and contractors, property inspection fees, appraiser fees, mortgage lender commissions, and bank refinancing profits -More headaches for property management companies having to navigate complex and controversial client demands on their property -Less qualified tenants using the first-come, first-serve basis for applications Now BEFORE EVERYONE thinks these laws are just horrible to invest here, I want to conclude with some of the major PROs of these laws:-Less competition from entry-level investors, meaning more deals will be had by liquid and well financed investors looking to scale with the roadblocks in mind-Higher valuation of rental property over the long term due to supply and demand constraints -More stability in the quality of management and landlord professionalism -More 1031 exchanges from older investors looking to move assets around more frequently to dump low performing properties -More incentive for real estate developers to only build large unit multifamily that will not have regulations for 15 years (from certificate of occupancy)-More expectation from tenant that they will receive an increase each and every year (more implementation, means more frequency to experience)As always there are two sides of the argument, but I firmly say that I can still be profitable and make millions of dollars here in Oregon, but with a little more caution and strategy.

That being said, whatever you did seems fine because you sound so compassionate.

I am sure BRRRR can be done thoughtfully and compassionately, but real estate investing in that manner exploits resources that others don't have access to at a greater rate (thanks to leverage) than even "traditional" (the last 150 years of) real estate investing does. 

But we try and mix 'being human and compassionate' with 'not getting screwed' when dealing with tenants that are experiencing one off 'adverse life situations'.  

Ironically I've noticed a lot of  people who consider themselves compassionate, concerned "Progressives" have these ventures.

Which led to conversations with 1800 numbers that finally garnered a compassionate CSR that really helped.

But society believes that Landlords need to make exceptions, they need to be compassionate, and understanding, and most of us are, but they also feel we should help them by letting them make payments to us until they get on their feet. 

If you do buy the property and decide you want the current tenants to move, please be understanding of their situation and compassionate, as well as stay within the law.
