Buy your second investment home with a mortgage (20% down) like you should be doing, then save your cash for your "dream home".You want to leverage your investment properties because the source of funds to pay the loan comes from the tenant's rent, not your pocket. 

In my previous county the winter temps meant that county code required an extra supplemental source of heat (electric whatever or a wood stove) as the heat pumps wouldn't heat a room under a certain temp.

In the past, I've found both to be good sources of information (as well as referrals) when it comes to learning the market and seeing what buyers are looking for and what and how they're willing to pay for these types of homes. 

Any suggestions or sources?

I am not one to have one source of income and be content. 

Anyhow, I am just saying selling and finding something else to buy in another area or state is more complicated than finding a property manager and a tenant for an existing building , so I wouldn’t necessarily use that as the sole reason to sell.

I always caution people to "consider the source".

So that in the event you want to do it yourself with permits or contractors are not available in a timely manner you can do it yourself do it right and get it done and move on to the next opportunity.NC LAW snippet:A person may construct or alter a building on land owned by that person without having a general contractor’s license so long as the building is intended solely for occupancy by the owner and his family AND the owner obtains all required permits.

Can you site your source showing just cause must be provided for a lease termination under the current statewide Covid rules.Granted if the tenant refuses to leave, an eviction will be required so the point is subtle in the case that a tenant refuses to leave at lease termination.  

I know it's probably best to not solely rely on the BP calculators, but just curious to see what others have found.
