The fact that the property manager leased it without collecting a deposit is a huge red flag when they are only placing a tenant. 

And, if you want to really see how LPs feel in a non public environment, there’s an “LP only” forum on Left Field Investors that discussed “red flag” sponsors that investors won’t work with again.

I got deep into loan types and rules and became a lender =) Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

I’ll be out of state, which I know is a big red flag for many.Well below 1% minimum of Rent/Property ValueHoping to self-manage (Yes, another big red flag)Loss of capital gains exclusionMONTHLY SUMMARYRental Income $3,500Less ($3,440) Mortgage (2,900) HOA (390) Rent Ins (150)Less ($1,155) Property TaxTot Exp ($4,595)Rev: ( $1,095) !!

So, a common action is what I call "the Red-Headed-Step-Unit".

Catch all the red flags prior to submission cause once you submit a file that has uncaught red flags, that's when your process slows and lender's get nit-picky.From a lender, I want you to work fast, if I am hustling on my end to make it easy for their processor and underwriter then I expect fast work with an open line of communication and I want my rep at the lender to be able to fight for me or my clients should an obstacle arise - which they usually do.

Her deep knowledge of the market allowed me to identify properties that were not only viable but held substantial equity potential.

I made my decision based on the fact that a) $5800 for a 90-day program was something I couldn't afford; b) $5800 for a 90-day program seemed VERY fishy/scam-y/pyramid-y to me; c) after scouring the internet for information, reviews, etc about the program, I found literally ZERO bad or less than 5-star reviews about it which - to me - is a massive red flag; no program, product or service is perfect, and the fact that they are making themselves appear as such really gave me a bad feeling about the program.

Some counties and states do not publish criminal information so you have to go to every county to search.If there are any red flags, I will conduct a Google search of the individual's name and the city/state they've lived in according to their application and their credit report.
