Contractors say the pad I got is already enough , its water resistant. 

Electric baseboard for an uninsulated space will be very expensive to operate and will require space that you may or may not have in your panel and pretty large wire to bring up, although if you use a small resistance hot water heater like Andrew suggests, and which might be your only option,  I guess you'll be running wire anyway.. 

   After mustering sum courage and getting out there researching, analyzing, and making offers i soon realized that the real estate business has no liniency to weather you’re a newbie or not.

I to focus on internet resistant tenants for neighborhood retail.

You can try to set it up at a local library or if the weather is nice enough a park, then there's no cost to anyone. 

The battery must be sealed or "tamper resistant". 

In the event of a market crash, there will be an uptick in defaults, and as a result, the MIP (mortgage insurance preimum) reserve will be drawn down.Luckily, right now, there is a surplus of funds in reserve (hence the push for lower MIPs earlier this year), so the fund can likely weather a small downturn.

If he shut it off, the tenant skipped on you and turn the power back on ASAP  to protect the property from cold weather damage.

If you can handle those AND the rent at least covers the mortgage, then you can weather any downturn.....Obviously no one know what the top of the market will be....but to heavily leverage at the top/near top of the market....and use that equity to buy at the top of the market is exactly what caused tons of people to lose it all when the market crashed.

The past of least resistance.
