Her realtor has made false claims such as we have to stage the house (she is allowed to tell us to take something down, move furniture, etc.. to their standards), we have to leave the property when they are working on it/showing it; If the house were to sell during our lease, we would have to leave the property because of the "right to occupy", or that the new landlord would be able to modify the lease.

I already have bedroom furniture for 2 bedrooms that I like (my BR and one other), so I am thinking I'd have one of my spare bedrooms unfurnished and the other furnished.

Unfortunately, we don't have any furniture in it yet!

Can stagers stage or remove furniture?

If you like the outdoors, I have to imagine the part of the country you're in is some of the best.

Creating a fantastic kitchen, changing all the lower level windows, cutting trees around the perimeter of the house, changing the roof and adding 100% new HVAC system. 100% renovation of the 2 bathrooms and creating a non existing outdoor patio.

Higher end interiors, outdoor space, basically any upgrade raises the costs.  

Often there are some other little benefits like this, parking, outdoor lights, fencing, landscaping (or lack thereof) Cons include loss of control.

Frankly I don't like showing during that time anyway with half the furniture gone, packing boxes everywhere, and what if the tenant loses an iPhone and thinks one of my visitors took it when my back is turned? 

Suffice it to say that any gas utilization equipment found to produce elevated/unsafe levels of carbon monoxide in flue gas is normally considered sufficient grounds by the gas company to shut-off gas to the property in addition to 'red' tagging gas utilization equipment responsible until such time the condition is addressed and no longer considered a threat to the life and safety of the building occupants.CO Poisoning Goes Virtually Undetected in a Professional Office EnvironmentIt's a cold, sunny Saturday afternoon in February and I've been given a reprieve in the weather thereby allowing me to use an outdoor scissor lift to safely access/observe a flat roof 24-foot above the finish grade (pertaining to the property for which I have been hired to conduct a PCA) without having to contend with rain/snow and below freezing outdoor air temperatures preventing a visual inspection of the roof much less conduct a higher level due diligent assessment of package rooftop units since gloves cannot be worn as they tend to interfere in attempting to access hidden system components such as air filter elements, blower fan motor assemblies, serpentine tube heat exchangers, etc. typically concealed from view in conducting a baseline PCA.
