Many flippers use private investors to fund deals, and structuring the arrangement properly is key to ensuring both sides feel secure.When pitching a private investor, the most important thing is to clearly present the deal.

What they will do if your DIY-ed cost segregation is audited is they will send you an engineer (you pay travel costs) to conduct a "real" cost segregation study and present it to the IRS instead of yours.5.

We charge one month rent and one month security deposit before move in (make sure payments have cleared before turning over keys)  One month security is max allowable by Delaware Landlord Tenant code.If they have a pet you can charge a pet deposit (again, by state code, DE you can charge up to 1 month rent)If separately metered utilities, make sure they've transferred them into their name by providing account numbers and also a copy of their renter insurance before move in.Good luck!

If it's vacant and really needs cleaning/repairs, then I'll wait until it's more presentable.2.

So you’ll be at least presentable when you apply for mortgage financing. 8.

I assume you could take a similar approach with Redfin, Realtor etc etc.There are STR sites like Rabbu that present deals regularly but not sure if these are sold furnished. 

They are harder to sell, which presents additional risk.Finally, there could be refinance risk. 

There's nothing like the present.

For most multifamily, I'm seeing on 30 year amortization to boot.Reminder for the lurkers that this has nothing to do with single family homes, 1-4 unit residential all gets residential mortgage financing, which isn't presently as good as commercial.Odd world where the 8-unit property has a payment that is less than twice as much as the fourplex, even though it pulls in twice the rents, and has less than twice the maintenance expense (the price of the fourplex is likely to be more than half the price of the 8-unit, and more than 1/5th the price of OP's 20-unit, holding constant location etc, but that's another rant for another day).

We stayed in touch with sellers, following up with them even when they weren’t ready to sell.We listened to their concerns, stayed present, and maintained relationships for years.
