You mentioned you're in a suburb, but in the city proper once a multifamily has lost its rights (usually due to vacancy) it is nigh impossible to get them back. 

You have to be unique, so others can’t reproduce what you’ve created.Non-substitutable is similar to rarity, but it also means that what your posting is relatively impossible to be replaced by something new.

It's not impossible nor is it very difficult once you understand the process. 

You also can’t plan for the worst case scenario because it’s impossible, instead you need to balance leverage/risk.

If an installer cant explain this to you sufficiently, shop somewhere else.As for the home value, I would agree that an additional 100k for solar alone is highly unlikely/ nigh impossible.

Living in the D.C. area it seems impossible to find an affordable home to flip.

In a better area if you get tired you can turn the property over to a property manager and sell when you get your price.In low class neighborhoods finding a property manager will be tough if not impossible.

Hello, I wanted to reach out to see how other independent landlords collect application fees.I manage the property from out of state, so physically being at every showing is impossible - and I don't necessarily want to tip my hand that I don't live in the immediate area to prospective applicants. 

It seems that in some areas you only find small multi-family in war zones or it's next to impossible to find a good one because investors have already ravaged the market.

It’s impossible to time the market with 100% certainty, so I focus on what I can control.
