Even for a regular investment property.

Screening uncompromisingly and regular inspections can go a long way to mitigating potential risks.

I've learned that it's a specialized type of line voltage thermostat, not compatible with regular low voltage Furnace/AC systems.

I'm strongly considering going prefab on a couple of lots ... if the price is significantly less expensive than regular construction. 

There may be some quick periods of no cash flow, but that should be made up at the end of the rehab... meaning make up for the loss of cash flow used for the rehab + regular cash flow, not back to neutral cash flow.

It's also a good idea to randomly call to see how responsive they are on a regular basis not when they are trying to get your business. 

Not to mention the upkeep of the new property, and its loan stress. 

Cash Flowing, learning the process on closing a deal was great and the upkeep/PMing part of the job is something I also find important to learn before thinking of scaling!

I use a lease developed in my state for realtors and is regularly updated to conform to ever changing laws.

I was just quoted either 7.0 or 7.625 on a DSCR loan which likely will have higher rates than a regular commercial loan.
