I'd use the enemy method over Airdna data.Higher interest rates, high property values, increasing STR rules and flat put bans plus oversaturation are things that make this a tougher business.You really have to do your research in identifying an area and a property that will cash flow today with no guarantee it will keep cashflowing in the future.

Matt, If you are looking at historically built properties such as your classic bungalows, 2-flat and 3-flats in Chicago, many of those properties were built well before the modern zoning code was established.

The land is 1 acre lot of flat land. 

I pay my contractor a flat monthly fee to work on whatever project needs to be worked on at whatever building of mine needs work so it’s hard for me to break this apart labor wise.

However, that's if your looking at a 10+ year hold - for right now, I think appreciation will be flat in the immediate future there, especially if builders are now discounting that area because they can't move houses.  

It works well for repairs.One tip though is use only flat paint on the ceiling and walls as flat finishes do not show imperfections like glossier finishes. 

Commission is a flat fee or %.

Furthermore, as the total dollar size of the project increases it becomes increasingly difficult to bake the necessary soft costs and inflated budgetary numbers into the loan (whether it is rehab or new construction). 

The policies can have blanket coverage for Additional Insureds (if required by written contract) and it is a flat fee.  

Biggest concern is how to gain cash flow in the current economy with high house prices, increasing interest rates and flat rental rates.
