I'm of course bias, but we get a lot of Nor Cal investors here because we're driving distance but have low property taxes (that do NOT reassess on the sale), stable job growth, employment growth, land constraints that drive appreciation, and much more landlord friendly laws. 

There’s no LTR cashflow in San Diego for example, but there is appreciation.

Again, this is possible only if I am allowed to ask the tenant to move out.I would really appreciate any input on this.

In my recent IRS audit, the agent appreciated that point. 

Appreciate BP!

Any advice will be appreciated, as I've never sold a house before. 

As long as appreciation and pricing pushes investors out of Boston to other tenant heavy areas that have job growth or easy access to highways/transport it will likely continue to improve.Very similar to the growth/improvement of Worcester from what Worcester looked like ~10+ years ago.

So you can use the seller financing to get in, put in some additional rehab funds to force the appreciation, and then refinance out once the property is stabilized. 

Appreciate the advice, Nadeem.
