Assuming your rental activities are considered a trade or business (many court cases address this issue), you would likely benefit from the home office deduction (Form 8829) and be able to deduct the prorated amounts of mortgage interest, property taxes, utilities, depreciation, etc. based on the proportion of your home office square footage to the total square footage of your personal residence. 

Directly beneath that is the Compact Property Record Card, which opens as a PDF.On the left hand side of that, you'll see the officially-official Building Characteristics and Total Living Units.If you see "Total Living Units 2" at the bottom of that section, that's what you want.

Yup, welcome to the fun world of sales tax in interstate compact.

I would of course pay proportionally less on the sale price of the property.

I have never seen a logging show that there was not some oil or hydraulic fluid spilled somewhere that just goes part and parcel with big ironalso on the fill situation that can take years and years to get clean fill put in there then it has to settle as you will want to make compaction you just don't dump dirt spread it around and wa la your ready to go.. other wise you have to bring it in  in lifts with water and compactor .. like dozer sheep foot vibrator rollers etc.. but if the city or country does not care its your risk for ground movement 

Am I blowing this out of proportion or are my concerns valid?

For example, If we take a full homeowners policy on the entire duplex we would essentially be covering the renter's personal property because the policy acts as if the entire large structure is our personal residence and requires a proportional person property coverage.

So the kitchen is not rightly proportioned to the rest of the home - galley style.

The success of your investment is directly proportional to the quality of tenants that occupy your property.

What I am  not clear about it whether cap rate determines the property value of property value determines the cap rateCap rate = NOI/PricePrice and cap rate are inversely proportional to each other.Let's say you are looking for a deal, the purchase price is 1Mil, with NOI is 50k.
