I have a small single-family home in Miami that is currently rented for $1,800 per month.

In winter time, you might check the utility company that powers the furnace once in a while to be sure there is heat so that your pipes don't freeze.Some jurisdictions require you to be responsible for the bills if the tenant does not pay. 

I could include heat in the cost of the rent as it only has one furnace.  

(I'm going to get heat on that statement) You do need to file your annual report and just put in zero for your personal property owned. 

It uses a boiler for all the heat.

If market is just heating up it may be a lack of urgency.

Important to distinguish the two as one heats a liquid to use for hot water/heat while the other produces electricity, so they're about as different as a steam engine and an electric motor.

. ** We ask for T24/T36** Income: 1) Rent growth - flat for next 3 yrs and inflation for next 3 yrs 2) Any other misc income increase by 2% aka inflation Operating expense (Big ticket items - Lets assumes its a C property)1) Tax - 85% of purchase price and then 3% - Texas is a non disclosure state 2) Insurance (General Liability and/or flood) (example: Flood insurance in Alvin area is ~20K for 40 Unit complex on top of general liability) 3) Make ready (assume 10 units per year based on 90 unit )~10% vacancy 4) Run and Maintain - based on how much capex you will be spending 5) Management fee (6% for your size) may be a bit lower but for now keep it a bit higher 6) Utilities 7) Professional service (attorney/CPA/Lawn/etc etc) 8) Marketing fee Capex:1) Whatever you think is needed (Check roof, water/sewer line/heating aka boiler/HVAC system/Foundation)

More extensive remodeling would add a 1bdrm apt and a 2 bedroom apt.Property is in a rural area, about 30min away from large ski resorts and 30min away from two popular destination towns that are turning into the cape for hipsters.Potential for the property @ 30% occupancy is:150*12= 1,800 (per day)(1,800*365)*.3= 197,100Operating expense are probably close to 100k, (high end) for heat, maintenance, cleaning staff.

Taking a macroscopic look at the Average Days on Market vs. the Number of Sales in Miami-Dade County from January 2016 through March 2019, we can see that as the number of sales goes up, for the most part, so too does the average DOM.
