I've been looking at smaller towns in Philadelphia (relatively easy to travel to) for flip and/or buy and hold opportunities and crunching numbers to get into a comfort zone for the right deal.

A grid-tie system is pretty much a hands off low maintence kinda thing.It all comes down to number crunching.

Your wife could definitely be more involoved with an AirBnB style setup and maybe that would get her more on board.Finally my personal comments would be to go to work finding real life examples and crunching numbers your wife can see rather than just discussing the concept with here.

They are crunching numbers, and numbers know no borders :)  There is very little to know that is different from state to state.

Then start crunching numbers on the BP calculators for the BRRRR or just a regular buy and hold.

If a LL doesn’t believe in charity or social commitment beyond keeping a safe building in exchange for the rent check, looking at this purely financial, some of the hardline answers may have never experienced a regional or national downturn and may not have stopped to crunch the numbers:-1 to 2 months rent deferred over the six to twelve months OR -3 months plus eviction costs and another month of vacancy after clean up lost with no chance of recoverySometimes good business is also good for people - so when we have the opportunity to do good, why not take it?

As the crunch came I had to sell some (& they had appreciated significantly) or a % share of others to get comfortably solvent.

No point of doing all the research, crunching the numbers, and getting it all down to an exact precise plan if she isnt even willing to even hear it out. 

I think that she is in a time crunch but that is no reason to repeatedly call me.

The credit crunch may cause some problems with small businesses and there may be closures that take some time to recover from.
