Admittedly, tax certificate investing recently caught my attention...I do believe Delaware lacks interest rate caps..As the usury laws were repealed in the 80's to lure financial entities. 

To piggy back on #5 above, what if the scenario were that I de-converted the property into a beautiful SFH, still met the 2 of 5 year threshold (probably when it was a multi family but maybe not) and sold it for a profit?

There is practically no job growth outside of NYC, except for Buffalo with the solar company going in.  

Now, is it difficult to buy a property that will cash flow in more expensive areas, like Delaware Ohio?

The site will also have a solar power setup where the building will store its own energy....The company produces battery cells, which can then be put into a variety of different forms, including for use in electric vehicles including trucks, boats and drones, and can also be used for energy storage, including for solar and wind power that needs to be stored and used at a later time.Arizona is a growing hub for the production of electric vehicles and its batteries.

The real decissions are in the year of "in service" determining the cost basis,,, where the years after just normal operations the accounting is much simplier, 99% of expenses are deductable as expenses against rent income.Knowing the tax code you can ask your contractor to divide up a small fix up into $2500 per each invoice to allow for De-minimus expensing of the whole turn over rehab. 

If $2500 would handle it, and if it were mine, I'd pay the $2,500 and have the place de-Ratted.If the others wish to live in these conditions and not pay, I would pay for it--because it seems like the only true "Solution".As has been said before Rats bring diseases, and 5/8" of gypsum ceiling board is all that separates them from your renters.Good Luck!.

There are a lot of homes in the De Armoun, Rabbit Creek, and O'mally that have little to no driveway, and it's normal.

Quote from @Jalen De Leon: I've heard many people getting an LLC and using it towards their rental properties.

The house I moved to was 500sq ft bigger, single story, has a pool and has solar panels.
