I'm trying to decide if the home that we lived in as a personal residence and then converted to a rental is still a good investment or not.

Other considerations things to look at include; are any utilities common (like paying for a boiler for all 4 units instead of individual furnaces), how does access/common areas work, do the tenants all have access to laundry, are there any common area utilities (light common area lights, electric or gas for laundry) that would stay in the owner name.  

When I sold the building within less than a week the new owners were out there installing a post box and had complained about it enough to the post master that he agreed to let them have one.

The owner has one goal, cash out of the property, and is offering seller financing.

A amnesty for unpermitted work can be a financial gold mine for some of these owners.

And the windfalls to the owners are life changing . 

We serve alongside a group of missionaries (we are business owners in the states with real estate and restaurants, but split our time between the US and Panama).

Identifying a d purchasing properties that are undervalued due to under market rents caused by owners with a lower purchase basis that are terrified of losing tenants and raising rents, will definitely provide you with immediate upside appreciation when adjusting rents to market rates as well as covering all your holding costs and a cash flow reward every month. 

Using that logic , maybe we should go back to only land owners can vote . 

The owner i met on site said I was the most trusted of all that she had met on site so she was confident in me.
