Starting from the basic, a house has laundry and a refrigerator and a place to eat, to be with your family.

If that number is greater than the purchase price of the house, then I would consider buying the property after looking at other factors (location, condition, neighborhood, zoning, etc).In other words, 6 straight months of rent should pay for the house. 

I prefer to use in- house platform messaging for basic messages, and actually write personal messages for anything else.

Then we get the house back. 

Typically you want the debt with the property and putting that debt on your primary is generally a no-no unless its short term.If I were you I'd pull out 70% equity from the rental property, go find another house under market value to fix up and force appreciation. 

2) Does old carpet bring the house value down?

A house 3 houses down was for sale and got bid up and we thought it went for too much.

If the homeowner has a material change in circumstances (transfer of title to his house) then he needs to inform his lender.

It sounds like the potential tenant is selling their house.

Currently house hacking while a BRRRR.
