Do most of them include the utilities in the monthly fees?

I've come across several products online that are basically a block with double-stick tape, but I like the tread idea on the block you have. 

For $20k you are paying to get access to her online library so you are basically teaching yourself.

From online research, I was able to find out that other cities in Ohio tax all your income (w2 & rental income) if you own a property there & some give you a small credit for taxes paid to other cities.My question is, if I buy a property in Cleveland (or a CLE suburb), would my w2 income be taxable in Cleveland (or a CLE suburb)?

Over all, a portfolio of DIVERSIFIED (as to residential areas) properties utilizing a buy and hold strategy should provide an adequate risk adjusted return without utilizing any other “opportunistic” strategies to “gig” the ROI.  

@Pretty Khare As Ruben and John mentioned above, you can utilize a cost segregation study on your STR property to reduce taxable income (or create a taxable loss) to offset against your W2 income, but you need to ensure you are following the IRS guidelines very carefully.

Well, do they have a job to pay that extra $200 plus utilities per month?  

For example, temporarily stopping utilities to their unit during a repair or if there will be loud noise or a major renovation on the premises. 

And once we get through this batch of cabins that came online, I think occupancy rates will return back to pre-covid levels - which were among one of the better rates in any other STR area I had seen.Its funny.
