Inexperienced investors tend to (1) get exited about deals without having the experience, knowledge or ability to properly determine if indeed the deal is good, bad or mediocre, (2) take what the seller says as gospel not realizing most sellers will exaggerate, lie and or withhold vital information to get what they want, (3) engage people who will provide opinions for free rather than pay a competent professional, (4) get emotionally caught up in the deal and very defensive when receiving an opinion or information that doesn’t support their dream, and rationalize that more experienced people who point out flaws are “jealous, negative or haters”.Btw, no one can provide any knowledgeable answers to your questions without first analyzing the deal, your ability to come up with a down payment, your credit capacity and banking relations, if you have a track record, your experience with similar property ownership, etc.
