I wouldn't call any of the fees you listed above as extra. 

Wish I had remodeled the space that is the dining room into an extra room to improve cashflow.

A small investment in the storage areas of your flip will show buyers you went the extra mile.Curious to see what everyone thinks!

So any extra pointers or tips , books, would be great guys I would love to connect and build relationships!

The northland MAREI meeting and the main monthly meeting at MAREI have a minimal fee, or for $99 a year you can attend all of them for no extra charge - northland is in person, the main meeting is still online, both are great ways to connect and learn. 

The reality is the opposite - if it's not in writing then the PMC doesn't have to provide the service or can charge extra for it!

My cautionary tale for shopping lower and you need 100% clarity on what's covered and extra fees.

I can certainly tell you in SoCal if you had a single family home with an ADU that generates an extra $2k per month in income, end-user buyers will not be thinking "I'd pay an extra $20k for that." 

In that case, using the cost segregation study this year might not be necessary because the extra depreciation would just increase your loss, which you might not be able to fully use right now.However, you have two options:Use the Cost Segregation Now: This would increase your loss this year, and you could carry forward the unused loss to offset future rental income.

I'm extra cautious when analyzing a deal like this, but a lot of them end up being great.For interest-only financing, negotiating some principal paydown is a good idea.
