these are public records - our records - and are available to us for free, or a nominal production fee.GIS records are usually free as well, eliminating the need for geocoding and including not only parcel boundaries, but a long list of parcel and building attributes, such as grade and condition, sq footage, yr of const, etc. very sweet, and open source GIS software aptly handles the task. re scrapes - you can easily scrape any site that is humanly accessible, even if robots.txt and other means try to keep you out - look at scrapy, beautiful soup etc along with some vpn proxy farms. or you can hire this out. and why scrape when the county will email you an 80mb csv?

It just sounded like you made attributions about the writer that weren’t supported.

We’ve found that attribute in tenants that can signal bad things ahead.

It's really hard to get the system to recognize that there are attributes of one property that might not apply to the one across the street.

Not only is your work highly sought after, but you will also know one of the most crucial aspects of real estate investing, and more importantly, the costs attributed to it. 

Without even knowing anymore about the property I wouldn't list it below $330k but probably $350k+, and depending on the attributes it could be a lot more.The rent is probably a little low.

When you realise this, and assuming investors value cash or equity (opportunity money) at a minimum of 10% return, you see that attributing a return to the equity in a property reduces the cash flow from the property itself. 

Are there certain attributes of a house that maximize this profit?

However, you cannot deduct expenses directly attributable to the rental period (rental agency fees, cleaning, and so forth).

You would have to look at the attributes of these specific areas and decide personally if that is what you are looking for.
