Another thing to consider... if there are mice, and they start chewing through electrical, that becomes your problem.

Now there was no mention of the engineered plans requirement for the 12+ requirement to my recollection, so I do call foul there. 

Stay away from electric heating - this is a tip for all investing to be honest. 6.

I assume it has sewer/septic, water and electric and they 2 tiny homes are plumbed/wired?

an inspector will tell you everything wrong with a property, from the minor to the major. so if the inspection report finds a bunch of electrical issues, yes, you'd need an electrician to tell you whether they are $200 fixes or $2000. 

My friend said his client nearly bailed when she found unexpected wiring issues behind the kitchen walls..apparantly the seller hadn’t touched that electrical since the Reagan era..but with a patient electrician who understood the local code and a carpenter who improvised a shelving trick in the diningrom, they ended up selling above asking.Flipping and building can get tricky, especially once you start thinking bigger.

****I am not a financial advisor or guru, I was just a dumb civil engineer who learned that you cannot push on a rope and dirt and water  = mud.

If it is block construction the engineers will make you beef up the slab and add piles to support the new weight of the second floor.

Here's what I've learned:Inspections Are Non-Negotiable: Always get a full inspection, but don’t stop there.Plumbing & Sewer: Have the plumbing and sewer systems checked specifically, as these are common problem areas in older homes.Electrical System: If the inspector flags any electrical concerns, bring in an electrician during the inspection phase for a detailed evaluation.

Electric baseboard is expensive and takes a while to warm up so on and off doesn't work.
