I'm looking for the most creative things people have seen or can think of, irrespective of how impactful it actually is to the bottom line or how much it would cost CapEx-wise.

It seems like this would be more on seller side.It’s not a deal breaker for the buyer, just a pain and occasionally a time suck, it absolutely can be an issue when you sell, not something that can’t be overcome but something that can cost time, money, effort, which again is why I’d just much rather be in condos than multi family all things equal, the per unit savings aren’t even that big in large swaths of D.C.

One month of vacancy costs you the mortgage payment, utilities, landscaping, etc.

I'm also wondering if anybody knows the costs and rules for bringing in water and power to a piece of land in these areas, I know it's different for each property but is there any possible way to get estimates on bringing in water and power to a piece of land I want to purchase before actually buying the property so I can create a general budget for buikding a home.

This will definitely be my last...The hotel is currently getting rebranded and unit owners have the option to upgrade our rooms using the hotels "discounted and preferred" contractors for the "low price" of ~160k (again, the unit cost me 400k and is currently valued at ~340k).

We know that a dual fuel system would be more optimal, but the cost of running a gas line and venting is likely higher than adding another circuit for the heat strip.Furthermore, we are looking for recommendations for an HVAC installer in Chicago.

Or would it be more cost-effective to replace just SEER condenser and evaporator coil for the AC?

The plan: I am identifying on/off market properties that are targets, will do all of the real estate work (listing, showing, advertising, vetting, etc) and will split the cost of the purchase of the home and the material costs for any needed repairs.The contractor will be subbing out portions of the job and be on site mostly full time until the project is completed. 

-Fixing a property upfront can lower your maintenance costs down the road. 

A hypothetical to see how people factor costs when rolling equity forward into additional purchases.For this example assume  you purchased property “A” for 100k, and put 25% down. 2 years later you sell it for 125k so you now have 50k (25k from your initial down payment + 25k in equity).
