My understanding is that the HOA is responsible for maintaining the retainer wall, but I wouldn't want to be out of luck should a snow storm or heavy rain damage break it down.My Real Estate Agent is assuring me that this isn't a problem as it's been professionally installed and the other neighbors have been living with the same retainer wall too.What has your experience been with a retainer wall?

If it was done properly the Optionee (tenant buyer) has the exclusive right to buy, so you'd have to purchase the right from them.Sounds like a mess.

And if used, how much does it cost to properly get rid of it ?

When writing a contract you will have dates and deadlines that you can get out of a contract with proper reasoning.  

The fact they are complaining online might be an indication the property manager dealt with them properly so be sure to ask the manager for their side of the story.7.

If a tenant gets a protection order, I'd change out the locks and probably install a security camera.

@Dan StrandbergUnless the process is different there, the inspection should include identifying the type of septic tank and drain field/system; evacuation; checking for cracks/roots/deterioration; type of material tank is made of; if it’s level; size of the tank- is it large enough for the number of bedrooms; whether it closes properly; whether water run through it drains properly; that the ‘hatch’ closes properly; setbacks from the home/boundary etc; and whether both septic and drainage meet any existing regulations.Hope this helps!

I am thinking about installing this product.

Then most large home improvement stores like Lowe’s, Home Depot, etc offer free installation on carpet if you buy from them.
