Personally, I think interest rates will be higher than today so it may be difficult to refinance your way out of the private money loan, unless that one tenant is currently paying significantly below market rents and you are certain you will be able to get much higher rents when that tenant eventually moves out and you upgrade to market standard.Doing a JV on a TIC basis would make the financing easier since your TIC partners would share in the ownership and mortgage expenses.

Many first-time investors start by buying a property in their own name, then transferring that title to an LLC later on.

Is there a way to get investors to bring cash to closing for Real Estate deal for a percent ownership in the property?

This property definitely requires more management due to the per room rental and the quality of tenants isn't always the best, the main challenge I found is that because the spaces are shared it is often difficult to have a tenant take ownership for an issue (smoking, noise complaints etc) and therefore makes it difficult to enforce rules or evict a problem tenant.

Sellers are required to disclose what they know, if you bought it on market, the sellers should provide a TDS (transfer disclosure statement) and SPQ (seller property questionnaire) if they knew about it.

I used cozy and everything transferred over.

But, that product was created by the Government to support home ownership for those that actually, well... didn't qualify on the regular market. 

Look around to see what you can buy with the money and with your bank if you can transfer the mortgage. 

My lender will only refi 65% of the purchase price/apprised value (whichever is less) if we own the property less than 1yr, and 80% LTV after 1yr of ownership.

Consult a CPA ,but S corp ownership for IPs is over complicating the deal.
