My husband and I are pushing hard to learn all we can and to grow our family assets, while still having time to enjoy our three kids and show them the world.The market here is very inflated and opportunities for solid cashflow suffer as a result. 

You don't want to both focus on it and have the business suffer. 

If the country goes into a recession, these properties will suffer. 

Here is an article about valuing multifamily real estate.What you asked for: (pros and cons of holding onto the small multifamily)Pros:Easier to manage yourself with less unitsAbility to diversify where these properties are and minimize risk (one property suffers, others can help carry the expense)Invest in each property as needed, able to spread out expenses over a long period of timeCons:You are not able to scale as quickly as 1 large MF unitHarder to self manage - expense for management feeYou will have to replace 5 small roofs instead of 1 large roof (this goes for A/Cs, Furnaces, Water Heaters, etcThere are a lot of pros and cons to both.

Of course, with only 1 vacant unit, it's probably a decent property in a decent market and location, not a D asset in a war zone.SFH isn't performing as well these days.Rents are going up, and finding qualified tenants is not a problem (we always have a replacement tenant lined up with lease signed and SecDep collected before the previous tenant moves out), but the metrics have suffered due to rising SFH values.Where we used to be at a GRM around 8.33 (or so-called "1% rule"); thereby yielding a 6.6 Cap assuming a 45% OER, prices have increased disproportionately to rents and our portfolio Cap Rate is now closer to 5.5% or lower (fact is, even if your SFH is fully remodeled like ours are and therefore have very little R&M or Replacement Reserves, NH RE Taxes are high enough to put you at or near 45% OER).Not that I'm complaining about our asset values heading up (it's about time the RE recovery came to the tertiary markets of NH), but the ROE it's causing is tough to live with; especially given the lost economies of scale when comparing a portfolio of SFH to a large MFH complex.

As Mike D. stated, I may be suffering from endowment., among other things.No capital gains to offset, but losses I can't take now will rollover, so eventually I'll catch them. 

Judge said she didn't move in,  so I really didn't suffer damages.  

I have been suffering from analysis paralysis for years.

They suffered through it until their 12month lease expired.

Here's an example:If Tenant fails to surrender the Premises upon the expiration or earlier termination hereof, Tenants tenancy shall be subject to the terms and conditions hereof; provided, however, that such tenancy shall be a tenancy at sufferance only, for the entire Premises, and Tenant shall pay Monthly Rent (on a per-month basis without reduction for any partial month) at a rate equal to 150% of the Monthly Rent applicable during the last calendar month of the Term.
