@Cathy LiRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

Select a larger area that is at least 30 minutes in each direction. with maybe a hand full of exceptions I am pretty sure you would be hard pressed to find a mix that represents the demographic cross section of this country and therefor a wide range of neighborhoods.

I just need to know is there any type of private lenders who specialize in much larger transactions with having windows on time of finish which I estimated at around 2 years.

It’s simple, brief and the right pair doubles your money each transaction.

Your experience with the DSCR loan process sounds frustrating, but it's not entirely uncommon for borrowers to encounter last-minute changes, especially in complex transactions like cash-out refinances. 

We just crossed the $5 billion funded mark a few months ago.

Uncertainty in Case of Disputes: Without the backing of a banking license, resolving disputes or seeking recourse for unauthorized transactions or errors may be more complicated.

The other fundamentals: professional photography, cross listing, reverse prospecting, etc as well of course as any decent agent does. 

The point being is that a lender that gouges a client is either getting their capital at a higher cost or they view the lender and borrower relationship as transactional and don’t see the lifetime value of the relationship, in my opinion. 

The only change is you're not working with a bank for this transaction (and, there are so many benefits from that).Ensure you have an easy and smooth way to pay your monthly payment to the seller/lender since you'll be working directly with the seller on that rather than a bank.
