In my experience, your typical real estate agent will probably know about most properties 8 units and less, because they are almost always listed on MLS.  

You won't typically get to choose your appraiser if you're getting a hard money loan so that's not unusual.

I have not experienced foundation issues representing clients, and the 13k quote is in the ball park typically it is at least 10k (depending on what is needed).

Consider factors such as the proximity to schools, parks, shopping, and public transportation.Property Condition: Distressed properties are typically in poor condition, so it's important to assess the state of the property.

I'd go with stained or polished cement With stained they can usually add and 1/8th" or so overlay (they then stain the overlay) so any preexisting stains or anything is fine Polished cement (in my experience) is the opposite - they essentially remove 1/16-1/8" of existing cement, so surface stains will be removed but anything that has really soaked through may still remain to an extent Yes water will get trapped between the LVP and existing cement/water barrier - for this reason I would not do LVP Could go tile - but why would you when you can stain/polish it for cheaper and not worry about cracked tiles years from now when you can't get a replacement 

I typically have some type of disclosure in the agreement written up with tenants on this type of situation..

Very weird... property taxes typically increase when there is a tax reassessment (renovations done, ADU was added, etc...) 

Rezoned multifamily land trades for minimum $120k but typically as high as $175k once entitled.

As an example in a typical syndication model the investors get around 70-80% of the profits.

So, for example a $500k sales typically includes 5% ($25k) in RE commissions (2.5% to each side).
