@Ryshawn Cousar  When you say how do you go about it that presumes a lot of things not the least of which is the seller sufficiently motivated to do a subject to? 

Aren’t the $200* per month for cap ex and 10% I take out for repairs sufficient to cover those expenses?

Do you think the $1m for commercial property is sufficient?  

It is in the PM's interest to establish a sufficient density of managed properties in a given neighbourhood to support a routine check. 

And I know that legally an email or text notification which the tenant acknowledged isn't sufficient right?

The NOI (Net operating income) needs to be sufficient to cover the payment and some amount of spread.To make the numbers simple lets pretend the payment on the 50K mortgage is $500/month and the 70K mortgage is 700/month (these are likely high numbers) if the rents minus expenses (excluding mortgage) net out to 750 then the 70K mortgage is pretty risky since there is only a $50 spread and the 50K mortgage is much less risky with a $250K spread. if these numbers held up I wouldnt buy the property at all unless I could get a 60K mortgage with a 600/month payment and have a spread of $150 and 10K in cash reserves. 

The tenant carrying insurance is not sufficient to cover you.

You see this setup when the soil is hard clay and effluent cannot percolate sufficiently for a septic system. 

Zillow, Trulia and such gives some information but frequently its not sufficient (ie Too few comparable home sold within the 0.5 mile radius or even the same zip code). 

Code Section 40-10-74 says: If the mortgage or other instrument creating a lien under which a party seeks to redeem is duly recorded at the time of said tax sale, the said party shall, in addition to the time in this title specified, have the right to redeem said real estate sold, or any portion thereof covered by his mortgage or lien, at any time within one year from the date of written notice from the purchaser of his purchase of said lands at tax sale, served upon such party, and notice served upon either the original mortgagees or lienholders or their transferee of record, or their heirs, personal representatives or assigns shall be sufficient notice.
