If it has gone up and down rapidly, then that indicates a boom/bust market (typical in areas without a diverse job market such as areas where all of the jobs are in tech, energy, manufacturing, a single employer or supporting those workers for example).

This depends on the neighborhood, material/finishes, custom touches, new roof, HVAC, electrical, plumbing, and ARV.

About $250 to $300 per square foot, because it is small which drives the per sqft cost up absorbing kitchen, bathroom, plumbing, electrical, utilities, basement, roof and impact fees into a small footprint.

Owning a car wash means you need to know plumbing, electrical, mechanical, and when to call the experts.

The other issue is the time and energy it takes to sort this out if you end up being reassessed (some people never have it happen.)  

The atmosphere was buzzing with energy as industry professionals mingled, shared insights, and forged new partnerships.

They mention termites, signs of water proofing in basement (we didn't waterproof), pluming and electrical repairs not disclosed, not disclosing a new roof, and they were suing for 150K on a 165K house...The truth of it is we didn't know of any leaks in the plumbing or the roof.

100% Understand.........I had 750 Tenants living in my MF Bldg's..........There are absolutely ways to get off the SFH treadmill, trading those assets in one shot and stepping into low-risk, single-tenant, 10+ year leased properties, backed by Nat'l Credit Tenants like FedEx, Amazon, UPS, and other solid companiesLooking for a better strategy, I combined my banking, real estate & Renewable Energy experience to develop the "Energized Real Estate" model. 

For example do you have a US based credit card, any type of USA loans you are paying, like car note, cell phone bills, electric bills?
