Is my debt to income ratio effected if I live in a house hack with rents?

Do you find it as effective or possibly even more effective?

People who think they are smarter than "cause and effect" are for sure going to lose everything.10.

Is the whole "dropping in to a random office with donuts" thing REALLY still effective?

I'd say the easiest and most effective way to get started is grab a duplex and rent the other side while also renting the spare bedrooms in your unit or finding a 4+ bedroom single family and renting out all of the other rooms that you aren't using.

Not all PM companies are effective at selling real estate.

Most markets are seeing full price or above for listings, so I am not sure this strategy is going to be very effective. 

Especially during COVID, thorough background checks will eliminate most problems.

At that point, my job is to contact every person who has expressed even a passing interest in the property and see if they want to beat the offer I have in hand.To increase your chances of winning, make the highest and best offer and eliminate as many conditions as you can. 

Do you have any tips on how I can properly analyze my deals effectively?
