Okay, can you at least get her to agree that this home is where you are planting your roots, and you won't be upgrading (or adding a new wing) when you get out of debt, or if/when someone gets a big promotion or bonus? 

One of many reasons to throw the 50% rule (and all other rules of thumb for that matter) out the window and learn to do your own grass roots analysis and critical thinking on investments.

Trees to close the limbs can fall on the roof, in a storm the tree itself can be pushed into the house and fall over, animals can crawl from the tree to the roof and get in the attic and walls, the tree roots can go under the foundation of the house or sidewalk and start buckling things or the tree roots can possibly break into your water supply pipes.  

That being said, had we not been steadfast about our choice to establish roots, we would have probably kept renting, or at least house-hacked.

I've asked the realtor/property manager to try to get to the root of "why", as I'm not fully buying into the reasons as to the sell.

However, my decision to purchase is always rooted in cash flow.

After they tell you something is plugging your sewer. ( usually tree roots)Just spend the second $200 and have the sewer cleaned and the job is done.

If your property manager has placed several tenants that trashed your units, the root of the problem lies there.  

I come from a background in real estate and consider myself very knowledgeable for some one of my age but when when you don't have roots in the market it helps to have a team that you can bounce questions off of and get help with the little things like getting the right contractor, property manager, title company, lenders etc. or  give you insight into the communities projects. 

So you end up with phrases like "chattel and goods" --- chattel having a French/Latin root while "good" having an English/Germanic root.
