I believe you have missed a crucial step here that possibly puts you in a bad position where it might not be possible to deny the wife accessDid either party give the 30 days notice required to terminate the existing lease?

. :)The closest to this that now exists, for the cash heavy but income modest, is buying out the PMI upfront on a conventional mortgage, rather than ever making a monthly PMI payment.

@James Wise  Per your request.Coming out of the late 1800s most of the major west coast cities that we know and love like LA  SF  PDX SEATAC were all subdivided by the same engineering firms  at least SF and Portlandia were.. this led to land speculators in the day going out into the Western deserts and other remote areas.. buying what were large land holdings , Spanish land grants and other lands that were not govmit owned.. then in the day you could simply create massive subdivisions buy doing basic surveys off of the base and meridian lines.. which all of the west is surveyed off of... this is called section land.then create these massive tracks of lots.. some were like up in the apple valley, Lancaster,  Barstow type areas mainly 5 acre tracts.. and were done on a grid pattern.. streets in ( mapped but not built)  and of course spiraled out of a small little town off the railroad track or the few roads that existed in those days.. you took your map and recorded it at the county, county was happy they just got 5 thousand lots they could send out tax bills on..

Bezos is building a $50 mansion here and is doing a $15 million renovation on his already existing house here.

Pull some equity out of your existing properties, use a heloc for part, go to a local bank see what they have to offer, private lenders etc.

How can I raise the rent on the existing tenants without being the bad guy?

Other people might have redemption rights, specifically all lienholders in existence on the date of the auction. 

We've been eying restaurants, especially QSR's but what we've been finding is that these are commanding a premium (especially if they're corporate tenants, not franchisees) and come with fairly low CAP rates and the ability to negotiate the prices is almost non-existent.

Also, there may be state regulations as this would be considered a form of submetering, and you need to ensure that you follow the procedures that are outlined for compliance.

There are over 100 points in the new tax law that specifically says that Treasury needs to issue Regulations on it (which is not a fast process).
