The goal is for that money to come back in 12-18 months (1-1.5 tenants).The biggest issue I'm seeing is that the unit was in trash condition and you replaced a refrigerator recently which now doesn't work.

My recommendation is that you require all tenants to sign estoppels prior to closing.An estoppel is a simple document that outlines the basic lease information so that everyone is on the same page before closing:Tenant names and contact infoMove in dateMonth to month or annual lease (with expiration date if annual)Rent amountSecurity deposit held by current landlordLast month rent held by current landlordAny delinquent/missed paymentsAny other agreements between landlord and tenant (for example, the refrigerator was purchased by the tenant and is his/her property)If the seller refuses to provide this for you, and will not provide leases either, then my personal experience is that you are probably going to inherit some problem tenants after closing, and you could be leaving yourself in a difficult position - that is, having to deal with multiple evictions, or worse, unlawful detainer actions (the procedure necessary to remove a person from a property when there is no lease on record, the person is essentially a "guest" in the property).You need to decide if the deal is good enough to take on this risk. it could still be an excellent deal, you just need to be prepared for some management issues at the outset - good luck!

Some of my rental properties already have appliances like refrigerators and dishwashers.

I understand the draw for "The worst town to live in, KS" is all the hootin' & hoolerin' and bullets shot into the refrigerator, the mud, the blood & the beer but what about other less lively places? 

So his cost will just be the condensing unit, refrigerant piping and wiring.

Was also curious about places that have appliances like a refrigerator, washer, dryer etc versus one that doesn't and if lack of appliances is another point that can be leveraged to negotiate rent down?

New refrigerator - $726.002.

Will it look odd having "old" & "new" refrigerator, countertops...... on the same years tax return taking full 100% bonus depreciation for both?

I totally gutted and remolded one room at a time making them into Studio/Efficiency apartments with kitchenettes (Small refrigerator, microwave, no stove). 

Refrigerators @ $200, Stoves @ $150 etc.
