It is not really a true electrical looking panel, I will take a picture and show you now.

They haven't missed a rent payment yet, but it seems that they're choosing to put themselves in a place of "financial hardship" by not actively looking for a temporary job although opportunities are increasing.It feels like i'm walking a thin line of either reducing their rent to reduce financial strain or possibly face no rental income at all due to their reduced motivation to return to work.  

May be pretty costly for an eviction and strain a relationship too.

If the house has old wood windows, you can break a pane and replace the glass for about $8.

Samuel, you're picking at a market with fresh wounds, 3 years might work but I'd generally not, that's cutting it too tight actually at 36 months, there needs to be a couple months to finance and close if everything else is good. 4 or 5 years is more like it since you're looking at newly foreclosed/delinquent borrowers.Also, an option sets a price up front to be sold in the future, you don't get the equity gained over the contract period unless you state that it is to be sold at a future based price, like an appraised value and doing so puts additional strains on a buyer as to the LTV.Lots written here about lease options, I suggest you study here and close the guru books as to the marketing aspects until there is a clear understanding of what an option is and the financing issues involved

I'd rather that than a strained relationship where they don't care about my property at all.My renters also are upper income renters so if your property is lower income, then perhaps you do need to convey a no tolerance approach.

My unit has double paned windows, not sure about the other unit.

You sold the first and killed them, then you grab the second one and showed them who the boss was...how did it pane out?

Old single pane windows.

It can strain the best of relationships so I can tell you from experience plan to go to a hotel or stay with friends for a day or two when the house really isn't livable and you see the renovation taking a toll....
