They apologized and we haven't had an issue since (2 months).I'm actually listing my college place duplex for sale right now, would rather move to my local town where I can better see and protect my assets and manage the manager... another red-flag, is it normal for a property manager to demand remaining management "commission" upon sale?

The 24-hour notice should in short provide you with 24 hours to file it with the court if they remain. 

it's a sacrificial metal rod that corrodes easier than the tank (by design), so that the tank itself remains rust free.so some tanks come with 5/8 OD diameter rods, others with 3/4 and I believe 1".I change them out every 4-5 years, they cost 10-20 bucks... 

Once split, confirm that the zoning is remains R2 (some cities have minimum lot sizes). 

You are better off analyzing the remaining life of major Capex components like roof, windows, plumbing, furnace, AC and have a reserve fund set aside as part of acquisition cost.

We want to request seller financing, in which we'll give them 50% of the purchase price up front, a 25 percent balloon payment in five years, then split the remaining 25 percent over five annual installments (not paid monthly, paid once a year, starting on the first day of the seven month after the contract is ratified).

I have a good lead on an off-market duplex with a motivated seller.

After we get rid of mortgage insurance our remaining gross profit will be right around $270/month.

They will contact the property manager and that should be enough to motivate the manager to make good.

It all depends how motivated the selllr is.
