Rent varies wildly depending on condition, who your tenants are, and where your property is located. 

I have been living in the home with no mortgage, the house is a 2 bedroom, 1 bath, 1300sqf, and in good condition.

I think they are a reliable company, but conditions are very different today. 

To assume the simplest thing and answer your question: if you're having a hard time attracting buyers, its likely the property is overpriced for its current condition/location/overall etc. 

They are unprofessional, with no etiquette. my poor friend, seeing her in this condition, breaks my heart. she told me she is afraid to leave the hospital in case these people try and kill her.

@Jordan Fujan In my calculations to buy a property once I’ve gone to the initial viewing I typically put between 5-7% for CapEx depending on the condition of the property and how much work we plan on doing to it upon purchase.

As for the practical concerns, in the dead of Summer, you have to be extra cautious about treating AC maintenance properly, because it can be dangerous inside a home that is not cooling properly, not to mention create conditions for mold growth.

When the tenant moved in everything was in good working condition. 

I would never do a post-possession without seeing the property unless we keep 80% of the fund on an escrow account contingent upon the seller vacating and the condition not being worse than described.  

My first property I bought here was in horrible condition and a complete gut job.
