It's her house.So what do I need to do to keep the house going without regular use?

You better bet the accountant documents everything 10 ways from Sunday, and cleanly to boot.

When this is all cleaned up wait 45 to 90 days before applying for loans. 

For example, give yourself 30 minutes in the evening after the kids are in bed and the house is cleaned (ie dishwasher is going, load of laundry in the machine).

I know condo associations have a  general meeting once a year and they have regular meetings of the condo board throughout the year whereby anyone can ask to talk to them. 

It might be a better idea to manage a regular Airbnb first, so that you can have some experience and can show it to your prospective leads.  

The quality of tenant is the variable, most people that need section 8 are good people who just haven't quite figured out how to improve their situation in life, they just want a place to live and will generally behave if they have a solid, clean, safe place to live.Make sure you check local laws and rules around section 8 so that you don't get yourself in hot water, perhaps get in touch with the existing owner/property manager and see what there experience has been with section 8 and especially the current tenants. 

Plumbers hate cleaning drains. 

I also own a small carpet cleaning company If know someone or ever need those services. 

The community was presented as a stabilized and clean park but had under market local rental rates.The community is located within the City limits of Declo and has all city maintained water and sewer lines.
