A room would probably make it more undesirable for the tenant.

I have my eye on a cash flowing rental property. The problem is that this beautiful property is in a neighborhood with no HOA, which allows the immediate neighbor to have boarded up windows, trash all over their front...

Yet we have a few parts in the inner city that are so undesireable, that a property will sell for less than the lumber in the front porch is worth.PS: it actually has crossed my mind to buy these properties and sell them for parts LOL 

Hi Linda,There are no "Pit Cats" only "Pet Cats.I think cats make way better tenants than dogs.No barking all day while the master is at work, no filling the backyard with waste, less likely to consume neighborhood children which leads to a lawsuit--unless it's a Tiger.You might want to talk to your insurance person about large breed restriction on dogs, and add a lease clause no puppies nor "any dog that management finds undesirable". 

I have a new tenant that runs the AC like there is no tomorrow 24x7 without any breaks understandably so as he works from home.The AC has aged so much so that it seems like it may not be able to handle such high usage as I have been observing some undesirable side effects on my electrical system which was not observed with my previous tenant who was a light user.

Properties of this nature easily become defacto transient hotels if located in undesirable areas. 

In some cases like undesirable condos etc 10-15% is considered. 

The few individuals who have been successful completing a transaction with none of their own capital invested usually fall under one of the following scenarios:1- They structured the transaction "so it appeared" as if they did make an investment of capital "mortgage fraud"2- They either assumed or purchased subject to an existing mortgage, with the seller taking back an owner financed second lien for his equity3- They have fantastic credit/track record/relationship with an existing lender and were able to convince that lender to fund without a capital contribution from them4- They syndicated the property to passive investors and received a "promote" interest or putting the deal together5- They used other real estate they owned as additional collateralBy far the most productive path to follow to obtain property ownership with "nothing down" is a property with the following characteristics1- highly motivated seller2- property is not in demand because of one or more of the following  A- low cash low  B - undesirable location  C- in disrepair3- An existing mortgage for a high percentage of the property's valueNote: once the property acquired you still have need for liquid funds for working capital, repairs, maintenance, vacancy contingencies, etc.   

they give you the most undesirable pieces.  

Your best option would be to eventually sell Paterson and move into another property that isn't located in a very undesirable area.
