A tiny house would work really well since she just needs a good size bed for days she's recovering from treatments and decent kitchen space for her highly specialized diet.

If the landlord does not take steps to exterminate the bugs, Tenant can contact the local health department.The real issues is that Bedbugs can require multiple treatments before they are eradicated

RE is only one side of the game, take care of yourself as a whole: education, exercise, diet, financial well-being. 

Bed bugs are a real pest and eradication is expensive.

Also, assuming you are still in your inspection period of the contract and have time, I would bring in a contractor or specialist to take a look at the water damage and give you estimates on what it would take to repair and eradicate mold.

It's too virulent to completely eradicate... 

Sort of like living on Reds, Vitamin C and cocaine; to living on the nicotine patch, a multivitamin and diet soda.

The VA loan limit has been eradicated.

It's like the diet and exercise plan for losing weight....it takes time and consistent effort. 

Also, why has there been NOTHING on diet and exercise to improve cardiovascular health?
