It's hard to stand out.There are some owner-occupied segments with people who share motivating factors for selling their home.Seniors with Long-time Ownership: often ready to downsize or transition to assistance.Homeowners with Low Financial Stability Scores (FSS): Struggling financially and likely ready to cash in on their asset.Both these categories have additional advantages in that they probably don’t haven’t been updated and may have deferred maintenance.

Even at the current below market rates the deal will still cash flows $130/mo per unit, after factoring in 10% vacancy and 10% maintenance/capex. 

@Travis Henry  Is the water billed back to the tenant or do you factor it into the price of the rent? 

Don't forget to factor in loan closing costs.Another note: if you fix it as a "flip" the property is going to be worth a higher ARV.

The main factor likely has to do with the lack of access provided by the owner/tenants.

You need to look at a bunch of factors - ARV, GRM, DSCR, Cap rate, EM, CoC ROI and so on.

In my area I wouldn't buy a 1947 house with a basement water problem.I understand there may be other factors that may make this a good deal though for you.Obviously there are things you could do, such as ensure gutters are unclogged and draining away, or dig up all around the house and sand blast the outer walls and coat them and install gravel all along the exterior walls, or put in an exterior sump, or have trenches cut all around the basement perimeter inside the house to collect water and then pump it out, or you could even toss away some $ by painting the basement walls and floors with special thick paint, but why make any of those steps your problem?

It's a combination of several factors.

And then once I check off all of those boxes, and once I sell the property, I get to wait for four or more years for some internal or external auditor or regulator to make sure I did everything right, and make sure I did everything the same way as I did for every other one I did.
