You may want to check your lease on this, but my guess is that you may not have given her enough notice initially on the rent increase? 

Only thing better would be initial deposit and then paid in full upon Certificate of Occupancy and punchlist complete.Of course, standard items should also be checked: licensed, insured, willing and able to pull all required permits, reference checks.I would also commonly avoid the cheapest bid you get.  

Here are some of my initial thoughts that has pretty well held solid and possibly even become more solidified. 

The current use of the property as a two-family dwelling significantly impacts its value and marketability, which is distinct from single-family homes.The initial appraisal comparing your property to single-family homes is likely an oversight, as multifamily properties are evaluated differently due to factors like rental income potential and investor interest.

Matt,I believe I initially misread your post, please accept my apologies!

For example, instead of an initial 6-month lease at $1,200/month, and then re-renting it in the summer with a higher rental rate, you could market it as a 16-18 month lease term (again, great suggestion by Tim) at $1,600/month with a "1 Month of Free Rent" special which you could either divide evenly across just the first 4-6 months of the lease, or prorate over the entirety of their lease term.  

Now it has CA code that protects them from jurisdictions that could advocate for their removal which would result in less safe units being available.It is an interesting dilemma especially if after the initial law they pass a subsequent law extending the dates.  

So in 3 years if you bought a $150,000 house, you would likely have accumulated $12,000 -$20,000 in equity on your $30,000 initial investment - not to mention your tenant paying down your mortgage, plus some really awesome tax advantages (3.3% depreciation, etc.), plus hopefully some cash flow!  

Aside from that, it sounds like my operation is quite a bit smaller than what you and your network operate with, but properties that are wholesaled are usually all cash or hard money, so the initial funding aspect usually isn't a roadblock.

Anticipation of these cuts initially moved mortgage rates downwards to their lowest in nearly 20 months.
