I just came across an older thread about wholesaling in Florida that basically said it's illegal to get a property under contract then market and sell it without a broker's license. 

OR Hire a really experienced Realtor that specializes in Investment Real Estate that has gained valuable contacts over the years that could provide you with access to their resources for free OR Work directly with a Real Estate Investing company with decades of experience that can provide you with access to their contacts for free2) Finding a deal: Here's a few ways to go about that - You or your agent can search the MLS and crunch numbers on property advertised on the retail market and hope to find a deal that all of the other real estate investors in Texas may have missed OR You can attend auctions and try to outbid all the other seasoned investors there only to realize if you win then that means you paid too much OR Have random wholesalers send you the one off deals they get under contract OR spend the time, money, and energy in trying to become a wholesaler yourself OR Work directly with a Real Estate Investing company that can send you the largest source of deeply discounted property sent directly to your inbox in the form of a daily spreadsheet.3) Estimating Rehab, Holding and other Costs: Read FLIP by Rick Villani and Clay Davis and The Book on Estimating Rehab Costs by J Scott.

The area is very seasonal, but the property has done well as a bnb for years without much marketing.

The plumbing, even if they didn't disclose, you need to prove they were aware of it.Lesson I have learned is if buying older properties, spend some money for a sewer scope as part of the inspection.

Basically, unless you're willing to wait for a 6 month seasoning period, it seems like the requirements are that your delayed financing loan amount cannot exceed your original cash purchase price (plus escrows, closing costs, etc...).

Will I need to season these funds for 60 days?

The office manager requested I file an extension because I cannot see a CPA until after tax season. 

Contributions can be made as both employee and employer contributions (since you wear both hats):The employee contribution limit is 100% of your w-2 wages up to $19,000 (or an additional $6,000 if you are 50 or older) provided that you are not making employee contributions to another plan (e.g. if you have a day job with a 401k plan). 

I am reading older posts and I see the consensus is that 10-12% is considered good CCR.

No seasoning is required.
