In order to get a response, and validity, they'll want you to actually provide the basic filing and proposal of what you seek to change at the property/building. 

I am a landlord, broker, investors, etc. and have section 8 tenants as well - luckily I have a good relationship with my tenants but man oh man... dealing with their case worker was almost like they were paying out of their own wallet for a rent increase when in reality HUD had updated rent guidelines.Do you not have an online portal or account that you can access the section 8 landlord portal via?

Now, they are contesting the eviction saying in their response to court that  I did not repair two issues because of which they are withholding rent.

Taking care of someone's asset is a responsibility that you should not take lightly. 

They no longer work for you, so monitoring a collection action is not their responsibility.2.

I’ve come across options like the Institute of Real Estate Management (IREM), National Association of Residential Property Managers (NARPM), and Certified Property Manager (CPM) programs, but I’d love to hear opinions on which have been the most valuable in practice.Additionally, any recommendations for resources, books, tools, or online communities that have been helpful for day-to-day management would be appreciated!

It seems I would need to submit around 100 offers just to achieve a potential engagement of 2% to 5%, with no guarantee of closing any deals.Thank you for your response, I definitely appreciate it.

In the past, Kipp has been very helpful and responsive and has given me help on repair costs from the past 2 tenants I have had that have been no good.

Ive also heard of online marketing campaigns--targeted FB ads--that can be configured to only target users on your marketing list.
