@Sarah MazeIt seems like you sell the house based on the headache and the amount of equity can be deployed to continue growing your portfolio. 

These regulations dictate the impact of a property on the environment and can have significant implications for property owners and investors.Environmental regulations can include requirements for the management of hazardous materials, restrictions on the use of certain types of land, and requirements for the protection of natural resources.

Based on all of your suggestions I decided to simply advertise the unit as an anticipated vacancy and mention in the ad that I can only show the place starting 07/01 and that it is available to rent anytime after that.

Does the local knowledge and contact base in a flat market outweigh the possible gains to be had in a growing market?

I need to find an asset based lender that is willing to base financing on the income of the property.

NOI, and thus cap rate, feeds into how much of a down payment is required b/c it feeds into the "sizing" of the loan.Many asset classes, like apartments and offices, have less than ideal in place cap rates today, so you need 35% or 50% down to buy them (unlike a DTI-based home loan, your personal W2 income cannot be used to significantly offset).

the book in the bp bookstore. i did the rookie boot camp 2y ago that i imagine this book is kind of based around, and one of the first steps was picking your strategy. the tough part is: THEY ALL WORK. but they all require different skill sets, different amounts of time, and will create a different-looking life for you once the ball is rolling. you have to lay out what skills you have, what you do and don't like doing, how much time you have, and what your vision is for your investor-life 5y down the line, and choose the strategy that aligns best with those things. 

Naturally I was skeptical at first, but I decided to purchase my first couple of rentals to see for myself how things would work out.

Based on the kind of return you expect, I would stand pat.
