However I have used some of apifys scrapers (for non real estate uses) and was highly satisfied with the value for the price: https://apify.com/tri_angle/redfin-search It looks like it’s for listed properties only?

I highly doubt many people have many a lot of money, because I have not really seen any in the FB group post things like... 

Quote from @Brandon Croucier: Hi Kathy, at the end of the day the mortgage industry is so vast & wide it's essentially like trying to navigate the Sahara Desert.I highly recommend working with an experienced mortgage broker who knows the ins and outs of the industry to place you into the most competitive product for you.More times than not, people save money working with a small shop broker.Kathy,I wanted to revisit this to offer a a tad bit more and Brandon above is correct.

Given the fact that the Baby-Boomer generation is retiring and interest rates are high (making a buyer's market) I should be in a good place.

Many experienced mentors in this group can help guide you in the right direction.I highly recommend saving as much as possible and setting aside a hedge fund for financial security.

Is this normal cost or high?

So, make sure YOU understand the copy & paste info below:Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Nobody wants to be around people like this, so I’ve had to lower my rent drastically and have a high turnover rate here.

Gutters are a must, I would highly recommend installing them on your property if you dont have them already.

It's a high risk strategy that you've chosen.
