Solar Roof Lease: Entered into 20-yr agreement at $10K/month to lease roof What was the outcome?

Because the cost of roofs, ac units, water heaters and so on don’t care if you collect $600/mo in rent or $3,000/mo.  

Maybe have a decent sized pool of cash to take care of the occasional roof repair or personal expense, but almost entirely in real estate?

It was an office building owned by a somewhat shaky business, but did have numerous long term roof leases for wireless providers.  

But ultimately all tenants leave, all debt comes due, and you're going to need to backfill it, so who is that, what pool of tenants could you consider?

., HVAC or roof replacements)?

I also invested in improvements: new roof, water heaters, other major appliances, and a kitchen renovation.Now, my situation has completely shifted.

However, you are always going to need to reinvest cash flow into your properties to be able to maximize their value, or reinvest cash to to new properties to maximize your wealth over time.  

Can I demolish the roof and build above it to raise the living space above the base flood elevation.

This of course depends on your starting bank roll - but if its like mine (under 100k) - Im trying to put as little as possible into it on top of initial equity and fees.this will likely chew a big hole in your ROI  (now if you are looking to improve value with a cash out refi or a great prospect comes along that needs combo new plumbing, roof, windows, foundation repair, etc - well just make sure you know what youre getting into and/or have a good contractor and finger on the pulse of the market when estimating the ARV YOURSELF - couple missed items and you risk having a bad first investment and not doing it again).    7) dont be scared be ambitious ( i should heed my own advice sometimes) 8) define numbers goals within your target areas.
