I don't want to waste their time because I know that typically there is a small percentage chance on the deal actually working out, but I don't know how else to accurately estimate renovation costs.I have looked at the rehab estimator tool on BP and try to ballpark it but ultimately I know that I will not know everything, and wouldn't want to botch my first deal off of not accurately planning for reno costs.Would appreciate any input - thanks!

Typically the main things you can lose profit on has to do with underestimating the cost of renovation; unforeseen things that arise; holding costs; or not accurately understand the market. 

I have heard about areas like Beacon Hill, Strawberry Hill, and etc, but I don't know if that is accurate. 

This is definitely worth trying if there are more accurate/higher comps in the area that your appraiser didn’t factor in.

I’m in Lafayette and can help you with comps and determining accurate ARV

Most of the time the reason is BS but every once in a while you get the honest "being kicked out"I require 5 years of address history on my application because previous landlords tend to be a more accurate reference rather than current landlords. 

This is my first time deciding to build a house and attempting to sell it from another state and I wanted to check to see if someone familiar with the Bella Vista, AR area could confirm the sell prices given to me are accurate. 

Best way and most accurate to get help finding the owner of a property other than using a skip tracing website?

Before you consider the above accurate in your state, find an experienced attorney who specializes in MHP leases.  

If I purchased a SFH for $30k I would be very happy.Along with that you would need to make sure that your cash flow calculation is accurate.
