Not one single strategy will work for every property. 

Similarly, if you put several Class D tenants in a Class A 4-plex, what do you think will happen to the property?

The land that this property was built on was approved based upon the capability of the land to support the septic needs of a specified-sized property. 

I’m a high income W2 earner getting hosed on taxes (currently own 5 properties).

@Jade Frank I agree with what @Dominic Mazzarella and others are saying here, but If you find the downside outweighs the gain and you ultimately decide to sell the property, Since the property was held for investment use it would qualify for a 1031 exchange. 

This was found through the City's tax auction, not much to negotiate it was a bidding process How did you finance this deal?

Assuming you have access to MLS (Multiple Listing Service, a place for agents to list deals).1) Look for deals that look like investor-type of deals (e.g. low purchase price, ugly houses, or sometimes MLS will even say what type of financing it is)2) If the buyer's info is there, voila.  3) Otherwise, contact the realtor to look for leads (that will be more of a uphill battle, but you never know...)

Purchase price: $100,000 Cash invested: $35,000 Sale price: $270,000 Hey BiggerPockets Community,I recently updated a multi-family property on a tight budget and significantly increased its value.

Creative strategies like lease options allow investors to control properties without owning them upfront.
