I have found a few forum threads where people who have bought TK rentals have found when the go to sell them that the house is not worth what they paid for it-http://bit.ly/1R68VZphttp://bit.ly/1MqwcWKI would like to avoid this if possible and wanted to get advice on how to properly determine the market value of the property.

Also I am a carpenter so I may be new but I ha e skills to bring to the table that may be able to help you out!  

We had delays with the contractor completing the work, unforeseen repairs required, a contractor scratching up the floor 2 days before the open house after they had already been refinished, and problems with the town & contractor over permits.One tip I would give investors, I would actually go down to the town with your contractor and make sure all the proper permits were pulled so you don't have any problems when you go to get your certificate of occupancy.

Even the smallest of imperfections will usually "telegraph" through the vinyl, and dirt can prevent the glue from adhering properly.  

@Amine E.

As others have said, deals like this where you must really go over all the details with a fine tooth comb can often end up being the most profitable if properly assessed.  

To properly understand the risk involved, look at the loan-to-value (“LTV”) ratio of the loan - if the loan has a 60% LTV there is a lot more margin for error than an 85% LTV loan.

My rehab is in the home stretch so I finally feel like I have enough time to really explore bigger pockets properly.

Then you still need to figure out what the rents will be with the heat on the tenants so you can properly calculate all of your pro-forma ratios upon stabilization.

There were definitely  A LOT of headaches and challenges along the way (which I won't go into because this post is already too too long) - but after total tenant turnover in the first month, I've got all 4 units rented to properly screened tenants.
