You'll only get into trouble by trying to guess on your own.Best thing to do is to hire a good General Contractor that has (preferably) decades of experience - no newbies or Handymen, Etc...They should be able to walk a property (< 1 hr) and give you a rough, but pretty close, price.

HelloI would like to know any land flippers that have experience in this area.

In my experience, appraisers these days very much like to engage in personal conversation.

We actually offer our clients renovation in house and out of experience for duplexes.

If anyone has experience investing in this area, I would appreciate some advice on the following:1.

It was first property we rented , great experience and we are learning from this experience. not sure about the other property with $500 below market that one is off market from Zillow not sure if it is rented or sth else. 

What has your experience been there in any??

You've mentioned Guesty and Avail as examples, but in my experience these are very different.

We had a fairly bad experience with one of the Hayward stores.. 

The second question is: Do you have experience as a landlord?
