Make sure you have an air-tight lease and also a house rules or house expectations.Has someone been renting in the other side and you are just renting your side? 

As @Daniel Sperling said, either get a standard contract that you can edit from a realtor you know or pay a local attorney to draw you up an air-tight contract that you can re-use once they know your goals - direct to seller, wholesaler, etc.The worst thing you can do is show up with a half-page doc for a seller.

Tenants used the propane for 9 years, then we decided to switch to heat pump with central air and stopped using the propane.

My property has central air and gas furnace.

Miami's real estate isn't just about buying and selling; it's about driving economic growth and fostering prosperity for all who call this vibrant city home.Time to Act: With the median time to contract plummeting by 17.9% and the median time to sales dropping by 5.9%, urgency fills the air as buyers and sellers engage in a thrilling dance of negotiation and decision-making.

Overall the air is full of potential and I asked my airbnb host to buy his place, its a larger lot w 2 buildings, hes renting essentially 4 rooms/studios out some without kitchen and theres a room for the 247 cleaner lady and a pool (tiny) in the middle, 2 parking spots, 450k.

This is how we found out that the tenant wasn't changing the air filter, which is his responsibility (we supply the filters) and he also couldn't figure out how to properly use the new thermostat.The filter was so clogged it almost broke the furnace!

A wholesaler doesn't have a buyer when they put the property under contract, so shouldn't even be calling FSBO listings if the person is on the DNC list.NAR video on DNC list:https://www.nar.realtor/window...Even if we all agreed this is a grey area, why not just air on the side of caution and respect peoples wishes to not be called?

If you already have a group of investors you work with, understanding their capital reserves, risk tolerance, timelines on return, and various other factors to help you understand what properties will be good deals for them and should help you narrow down your scope.When thinking about what tools to use, think about what you need to get done.As a wholesaler you will need to find leads on potential investments, run numbers on investments, put together investment packages for your investors, etc.Lead Generation:- Can be done on MLS, Auction sites, etc but remember competition will be high here- Pre foreclosure lists- Drive for Dollars- Social Media Campaigns - Billboards & signsProperty / Market Due Diligence:- Bigger Pockets Tools- Air DNA- Reventure App If you would like to connect and discuss in detail I would be happy to brainstorm.Good luck

You could add a ductless minisplit system that would provide air conditioning and also heat.
