The home is cooled with window units and heated by the same window units/ceramic wall mounted natural gas heaters.  

I feel although this secret room would be vented there is a lot of radiated heat in this room. 

(Be aware of heating systems with steam boilers, they can be problematical and do not always heat buildings consistently.)You will want to develop relationships with several lenders.

There are services that only assist with heating/cooling related bills, some that deal only with rent, some that help with children-related bills, etc. 

I am an Investor & Licensed Real Estate Agent, I work together with clients who want to invest and search for deals like this all over Miami.

Otherwise when they heat up, they will emit cigarette smell.

My small town doesnt have the density that Miami does so I can only get two units on a 10,000 sf lot, hence why I'm doing a duplex.

Hello Everyone,PS:UPDATED(MODERATOR please move or delete this post if needed this may not be the correct section)I would be interested if you could share your experiences about doing short term rentals such as AIRBNB etc in SOUTH FLORIDA around the Miami/Fort Lauderdale Area,mainly interesting in the numbers to compare with a traditional yearly tenant,I know you need to check for zoning restrictions,that a manager eat a bit of the cost and that doing it yourself is pretty demanding and stuff like thatBut it really is the return you had that interests me and to know if you would switch to something else or doing it again,I see tons of beachfront studios in the fort lauderdale,hollywood,sunny isles etc available in the 100K range that seems to be more like Hotel rooms,but if you get a constant traffic with very little vacancy it seems it could definitely makes sense doing it and tempting the adventureThanks to everyone
