Areas like Fountain Square, Bates-Hendricks, and Irvington have seen revitalization, but you’ll want to do your homework on specific blocks.

If your current guest calls Airbnb or Vrbo or wherever they booked, the platform will cancel and block your calendar anyway until you can prove you are free of bugs. 

makes about as much sense as me standing in McDonalds drive thru blocking traffic demanding everyone stop buying burgers so I can force McDonalds to discount burgers 20% due to lack of buyers....All these people howling there needs to be more rental units so rents are cheaper. 

One thing is upper darby Varys block by block so definitely scope out where your buying cause some parts are worse then others.

Loan:$20k down, 3 year balloon, 4% interest amortized over 30 years.Sale: $727,000This was a 4 unit property located a few blocks from the beach in Panama City Beach Florida.We decided to sell due to the amount of work needed with no renovations and sold for $727,000 less than a year later.

That's my mental block.

Haha,I was famous there once upon a time - https://9now.nine.com.au/the-block/i-doubled-my-money-on-aus...Negative gearing is buying a property where the rent doesn't cover your mortgage.You tally up the total monthly losses and let's say you where negative $30,000 for that year.You earn $100,000 from your salary that year.But you would only pay income tax on $70,000 as your property was negatively geared by $30,000 for that year.Make sense?

Assuming the floor is concrete, you're probably going to have to seal the floor to block the odor.

My duplex had an additional unit built in the basement and discovered by city inspectors when a neighboring squabble caused buildings department to check houses on the block and my house had 3 mailboxes out front.

Put up a fence or plant some trees to break up/block the view of it.
