And please give me recommendations of where I should start to get my footing. 

Once you have a substantial sample size, itemize them on a Google sheet form and compare the Price, Price per square foot, Lot size, price per bedroom, etc.

This 4,617 square foot beauty, sitting snug on a 0.26-acre lot with 6 bathrooms, seemed like a promising catch when I snagged it off-market back in September 2023 for $610,000.

The properly sits on a large 28,480 square-foot lot zoned for office, creating the potential for re-development as a medical office expansion.

rents are higher here by far one of the most expensive markets to live. lease price per square foots can go as high as $8 per square foot. if you live far away it'll be cheaper or you'll be living in a older unit. depends on your budget really 

I am just trying to get my foot in the door to get the ball rolling.

But also don’t want to shoot myself in the foot by buying a bad one!

I wouldn't trust their ROI figures with a 10-foot pole, unless the price is very low, which I doubt.Finally, the website has alarm bells all over:- no about us section so we know nothing about the developer;- no contact details;- no English version for the website but titles in English while everything is in Spanish; generally speaking, it looks like a bad job done by an inexperienced VA and not vetted by the owner;- how are you gonna communicate with the developer in case of problems if you don't have a phone number and they don't even speak English?

For those situations, I would typically budget about $.50-1.00 per square foot of wall space (or about $1.50-3.00 per square foot of floor space).If the wallpaper is difficult to remove, it can cause a lot of damage to the walls when it's removed, to the point where skimming over the old sheetrock won't work. 

You jumped into the deep end of the ocean when lots of people just talk about investing and won't go near a shallow 2 foot pool.
