The operation was checked and It was correct, they will have to cover the hole in the wall to dry the water that was on the floor.

I did have the handy guy clean and dry off the area on two or three separate occasions.Moving forward to two weeks ago, they are complaining of mold and now sickness, I hired a property manager to deal with this. 

I like things cut and dry so there's no opportunity for misinterpretation of who is covering what.

Sale-Leasebacks have inherent challenges because the tenant/seller is incentivized to market the property in such a way they get they price they want, but if the entity who signs the lease is weak and there's no personal guarantor, they could stop paying rent the day after you close leaving you high and dry with very little legal remedy.I don't know your market, but in my eyes, any 10% cap offering is either an extremely weak tenant OR a tenant that has very little term remaining with no plans to renew.If I were, you I would very seriously consider how much I like the real estate and what my odds would be of refilling the real estate with the same or better rent and/or a better credit tenant once this tenant goes belly up.

Have been doing this for a few years and there has been lengthy dry spells like this month.

Other areas were your relying on Wells that are very expensive and or you pay 15k for a dry hole.. etc etc. there is basic due diligence that needs to be done and relying on someone else to do that for you is frankly foolish.

You dig a dry well do you know how deep you can dig into the water?

The leak was pretty severe and ended up going into the garage, so we had to dry out and ventilate the garage as well. 

This gives you the dry powder you need if a good deal comes along or unexpected expenses and you keep the existing low mortgage rates and do not increase your payment until you use the HELOC.Consider how you could increase the cash flow on the existing properties and if you have the means to pay off one of the houses to increase the monthly cash flow that way.

My old sources recently ran dry and I had to venture out.
