100%, that is for sure an option that always exists but I am mainly discussing on market/MLS properties but at the same time, with more inventory and slower market, even the off market/verified lists take longer to sell which gives investors that extra time to get this research done correctly. 

A great flip on the wrong block becomes a liability.Have your brother drive streets at different times of day and rate blocks A–F for:• pride of ownership• renovation activity• rental comps• safety/foot trafficDon’t analyze houses until you know exactly which micro-pockets you’ll target.2.

TO be clear, I'm not saying its a bad thing at all, I think its a great thing, but if you're just looking to buy something to only make a profit and cash flow, it makes it very challenging to compete in a marketplace where not everyone has that same goal.

Otherwise you usually have 30-60 days to move in after purchase.

I give tenants 90 days advance notice and ask them to respond within 30 days so they have sufficient time to think about it. i.e. if they want to continue then sign the lease or if they want to leave then give a 60 day vacate notice.

What you are finding out is that spreadsheet cash flow is not the same as real life. 

What works for me is keeping it real and consistent online, educating people every day with real life deals, problems, and solutions.

Regarding the smoke detector, the may be an exception for foreclosure properties since you don't/can't have access. you could make the argument to the bank they must give you access to inspect the smoke detector and do inspections at the same time. how can they give you access if they don't own it?

I wouldn’t be surprised if others are doing the same as STR revenue softens.3.
