Lenders usually do not lend against real estate when the owner holds a tax deed because the tax deed does not create marketable title, or enable issuance of a title policy.Quiet title actions are court proceedings that ask judges to enter orders stating a grantee holds superior title to a property.

Usually, a pest problem is related to something the tenant is doing. 

Month to month leases are not short term leases, usually they are 1 year leases that are transitioned into moth to month when the lease term expires thus making this completely different from Air BnB style rentals

From my experience with Airbnb, most guests that I have booked my place are usually here for a show at Red Rocks, hang with friends, downtown drinks/dinner, mountain trip, etc. 

I usually handle absentee properties so this deal through me for a loop.The home is worth 400,000 as is, the owner owes $310,500 to the bank and had $88,500 in equity.

Syndications require a private placement memorandum (PPM), which can be costly and usually only make sense on larger deals. 

You will usually need some sort of connection with a private money lender before they will loan to you.

A duplex will usually give you a private yard and/or private parking.

I think there are a lot of people that get discouraged when they don't find a deal the first day or two but it usually takes weeks or months of constant hustle to see results. 

If you pay that, you usually end up getting the place.
