I offer them to stay 20 days for free, but charge rent if they stay longer after that.

To be compliant you dont have to scrape walls or do extensive repairs in most cases.

Why build a wall when I could make my table longer for others?

I have an inspection scheduled for tomorrow for the termites, but he said without tearing back walls it's tough to know whether they're active or not. 

It's the visual thing for some people mostly, with such small wall space having it right there in your face isn't ideal. when at all possible, every flip will just get duct work and standard air conditioning. 

When you start opening walls, a lot of issues that, based on the visible condition of the house, were assumed to not be present, are.Bids coming in over budget

I had one friend who tried this and finally went to go visit the property and it had holes in the walls etc that the contractor never fixed but they did not know it until they visited

But the Wall Street Journal had a favorable feature on him in July. 

A key improvement was removing a wall to create a larger, open space, significantly boosting its rental potential.

Curious thoughts on adding an EV outlet (no charger) for tenants to bring their own chargers?
