To me, that means you don't it and have as much claim to it as I do to my neighbor's property.I lived in a community in PA that had a deed restriction blocking construction of sheds and other things on all of the nearly 400 properties in the community.

They'll finish the block and then it'll take a month before they start framing - for no reason at all.  

Floor is just painted concrete, and that includes the 300sf which the county assessor counts as fully finished.I'm reading that DSCR rent appraisers may not count partially finished space at all, and count fully finished basement space at only 25% of the rent of main floor space in the same house.What are your thoughts--is this how it typically is for DSCR rent appraisals?

It is easy to spend a few extra dollars fixing a duplex up and be the best on the block.  

If you want to block it off, I'd do something similar to your diagram on the bottom left where the door to the new bedroom is closer to the bathroom. 

This also gives us the flexibility to block it off for friends/family when they visit.

We had a ton of investors go to Philly because the taxes are low, the prices are good, but you do have to study the blocks and drive them.

Travel to get the feel Once done with 1 and 3,  fly out in the area and spend few days to drive around neighborhood and take notes per home/block/street on what I feel.

For at least half of nearly forty years life I've lived and invested in property within a block or short walk to the beach in South Florida, Southern California, Southern Oregon and Northern Baja Mexico. 

Our plan is to sell or refinance within 15 months targeting a sale price of 3.5 million.This property is two blocks from the beach and has a high demand for short term rentals.
