I hope you or someone is at least keeping an eye on your properties for break ins, squatters, roof leaks, temperature control, frozen pipes (if in cold climate), if you have a basement and sump pump goes out leading to water damage etc.I just talked to two investors in California that have let their properties sit vacant (no mortgages so paying property taxes and insurance).

Binghamton was recently recognized as one of the fastest-rising markets for local home prices.

The down sides to an all concrete house is temperature retention good or bad. 

Significant and sustained population growth leads to demand exceeding current supply, causing prices to rise until there's a rough balance between sellers and buyers.

But when I google "why are housing prices still rising in LA despite population declining", all of the answers start by explaining the imbalance of supply and demand.

Where I'm from people do not like living in apartments/high-rises and so on, but I think more options like that would make housing more affordable to the average citizen.

In larger cities like Vancouver BC, the newer condos are smaller so they can get more units in each high rise and because the cost of housing is really high ($1.3M for a 820 sq ft 2 bed/2 bath condo). 

The community property exception does not require that the operations rise to the level of a trade or business or that either spouse materially participate in the operations. 

- Dont be fooled by rising prices - they may be lagging the rest of the area for a reason!

cash flow has just been hit hard everywhere with the rise in interest rates. the properties in my portfolio that cash flow the most are at interest rates that it's not possible to get anymore - low 4s - and somehow there is still tremendous demand for properties that won't cash flow or break even, which is what you're finding.based on what you've said about your current situation... i don't have a good answer for you.
