I typically use $30/sq.ft to estimate fix up costs.

I just don't know how much of an issue it actually is as of yet.I have thought about getting an estimate from a foundation repair company, but at the same time would much prefer to have an independent analysis of what exactly is needed instead of hearing it from someone who can easily inflate the situation to improve their own profit.Thanks for any tips!

I wouldn’t recommend using Zillow for this because I would estimate 80% of the data is very old and wouldn’t apply.

We purchased our current home 4/7/17 and we are estimating we have gained right around 20% in equity.

www.renovationgurus.com They even have a great tool that can show you how to estimate your renovation work fairly accurately. 

@Keegan Lunsford , can you please send me a list of your contractors as well  and maybe indicate in the list which ones charge to give estimates and which ones don't?

There is no chance I would make that investment. 

My initial estimate is $5000 per, up to $10000 on some.

There is little chance that the current tenant will be able to purchase.... he apparently still has a renters mentality which will remain while you try to push this rope.

Even if you don't have the rent roll, get an estimate of potential market rent from apartments.com or and rentometer.com.
