Generally speaking there is a reason why Condo's are of larger size.

Quote from @Enrique Toledo: I came across a really good seller financing deal and I would like to purchase it as my first deal but I don’t have enough money for the down payment.can I use a lender of some sort to give me money for the down payment?

Just curious if they do all properties or just a larger property.

Also, going to local RE meetups may be smart to see if any investors have good plumbers/contracts they use.What sort of alternative financing options?

Although it is possible to do everything 100% remote, most people I know who are self managing do come on site for a few days or weeks to meet and sort of interview the team they are building.You will need trusted cleaners, handymen, and also good recs for trades i.e. roof, plumbing, HVAC, etc.If you need home setup in most markets there are designers who will handle the whole set up for you, and I would want to interview them as well.  

For any CPAs out there, what would sorting through this and completing a 3115 cost today?

But even then, seller financing is rarely substantially better than another investment they could make (including trust deed lending, which will often be at a higher rate than seller financing)In my experience, the owners who find owner financing advantageous are at the ends of their careers and are not interested in looking for another investment (other than the usual retirement funding sorts.)

Umbrella insurance is usually a very large policy of $1 million or more, extending your coverage for larger situations.

Currently I own a large real estate company and still get some great value out being in his inner circle of real estate operators. 

Also--similar to apps like Facebook and Twitter--I can almost guarantee that a larger pool of people would seamlessly utilize their phones to vote/like and comment on the forums.
