....all based on 400K value and also taking into account receiving 70% of total value for each option. 

These have been really beneficial so far as well as the advice I have received on this post.Thanks to the postings I seem to have some more due diligence that I need to do to determine the size and exact markets.  

We listed FSBO  and received a full price offer within 10 days.

@Brooke McGilvery the agent's commission comes out of what the seller receives from the sale.

Yet 1/1 condos at around 1k Sqft are going for $240,000.00 (https://www.redfin.com/FL/Sunny-Isles-Beach/19390-Collins-Ave-33160/unit-1504/home/43318747).So why would I not grab that lien, drop $200,000k into the condo, and turn around and sell if for $240,000 and make $40,000k?

For those of you who have been doing this for a long time or have experience/inside knowledge, if you had $100k, where would you put it, spend it, use it at this point in 2018 to grab some great funds or gains? 

Apart from those sections, other parts of the city are attracting significant amounts of attention.

If paying those fees are greater than the commissions you receive throughout the year, it's probably not worth it. 

We receive payments in Crypto, cover expenses using Crypto, etcI have a chunk I want to diversify into real estate.

I received 250 dollars off closing costs once by opening a checking account and went a head and used that account to hold rent deposits from that purchase.I once read a story off BP were a guy was told he MUST open a checking account to close a mortgage by a community bank.
