What RS does, it creates a tangible new niche market for a rental property that any property shall be as transparent as possible.Maybe similar to CarMax in used car market (except Carmax makes an undisclosed profit).At the beginning, I'm also reluctant to have an investment with RS but when I attended their office, meet their officer, there's no selling pressure, they're pretty much only the broker of the open rental market. 

I spoke to the CEO only one time through text and phone call and this only when he was pressuring me to send another $15K to complete the $30K commitment fee.

If they do not pay I suppose I can put pressure on them by sending letters stating they are in breach of their rental contract by falling behind on their water/sewer bill.

I think a lot of listing coming out today will become short sales in coming months, exerting a downward pressure on the market.

In my experience, developing a relationship without pressure works as you don't come off as a shark/slime ball-LOL. 

I can promise though that there will be no sales pressure from me for our services at the bank.

Incorrect drainage is the issue for many older homes having foundation cracks as the added pore water pressure from the rain creates an uplift force and can cause differential forces on the foundation (a foundation's enemy is not always more force but it can be less force to retain the foundation as well).Just know the wall wont crack on its own.

Could be that the last time it was repaired, there may have been multiple leaks and the technicians did not pressure test adequately or at all and frivolously charged the system.

I've heard of pressure loss issues and false shutdowns, if it would even work at all. 

I would also encourage you to check out any of the REIA groups in the area including our local Fresno Deal Seekers meetup - we get together once a week to network and talk about real estate, partner up, share deals, and analyse properties - its a great place to meet other investors, make great contacts and ask questions in comfortable no pressure environment.
