This isn't rental property related but it is real estate related, and I am hoping the community can help point me in the right direction to whom I can start asking the right questions as to how my husband and I can take over his parent's mortgage payments. 

I have been seriously thinking about improving my parents rental property (which I live in) and adding a 1/1 in the back or 2/1 if possible.

Papas said the majority of active listings didn’t have strict cancellation policies.Hosts’ sense of control disappeared as the crisis took hold and the company stepped in to ameliorate travelers’ panicked cancellations.

I lived in the neighborhood so it was easy to control.

You should always keep control of the escrow you are using. 

As an owner-occupied property you'll qualify for low-down payment loans. 690 isn't great, but it's probably good enough to what you're looking for, if your DTI isn't out of control right now. 

Go to REI events, meet more people, bird dog for some investors, but do not sink yours and someone else's (please not a parent) into a flip with no experience.

There are pros & cons: little to no effort on my part, little to no control on my part, the location is mostly irrelevant (I have investments in 9 states), you need to be sophisticated (knowledgeable), you have to get access to folks that are creating deal (folks that you develop a trust relationship with!).

You can raise rent once every 12 months, but there are limitations, especially if the building is rent controlled.

@Nick Rutkowski Ok, I hear you, but I'm nowhere near the point of having the money to invest in something like that, and I want to get out of my parent's house.
