I can give you my more specific opinions if you let me know if you are accredited or non-accredited?

It also weeds out the non-serious people.

Search for those that allow non accreds they are out there.in our world we do ONE note one investor and you don't have to be accredited.. although usually a waiting list to get a note but they get filled in 30 to 45 days..

Sam Hendricks Option fees are non-fundable and don't go towards the purchase.

Your Taxable Value on this property is $ 71,500.So here how it breaks down for your taxes in Rock Hill SC:$71,500 x 6% = $4290 (6% is non-owner occupied taxable rate)$4290 x  .4108 = $1762.33 per year  (.4108 is the current 2017 millage rate)So your taxes are going to be $146.86 per month.Here is a copy of current millage rates per county in my area.After looking at your numbers I would think your rehab budget is low.I have a lot of property in Rock Hill and you need to make sure you get a home inspection. 

Non warrantable condos are always an issue, there are lenders that will finance them, at a slightly higher rate of course and usually with a larger down payment.  

There aren't really any formulas for this, your best bet might be to look at the pictures in rental comps other than that I would estimate the difference to be about $100 in rent for every $1000 of rental value if everything in a non-updated unit is clean, usable and looks reasonably nice.

If you get a conventional loan for a Non Owner Occupied (NOO) property, then you wouldn't need to live in it at all.

I could point out the differences in fair housing laws between house hacking and non OO renting.

I had identified a few properties on the list of interest with a non-redemption strategy in hopes to initiate foreclosure after the 2 year redemption period, here in New Jersey, thereby acquiring a property or two with future plans to fix and hold or flip, etc.
