@Brie Schmidt loan limits for conventional mortgage?

There are other low down payment options using Conventional financing, and even on 2-4 unit properties if you are a FTHB.The best thing you can do is talk to a rockstar Loan Officer in FL that is familiar with all of the loan programs and local grants. 

Why not just do a normal conventional refi? 

Do owner financed houses go for more or less than conventionally financed houses?

6.125% is not a bad rate for a commercial/portfolio (Non Fannie/Freddie) loan.How much lower are you expecting to get by refinancing since you can't qualify for conventional?

I've done all conventional loans up until this point and am seeking a little input/guidance when it comes to more creative ways to finance a property.I am attempting to purchase three homes from one seller. 

I've read a lot about the asset protection plan of buying a property in your personal name with conventional financing, then quit claim the property into their LLC.  

Based on many factors (location, condition of property, inventory, demand) it may be best to do the minimum. 

One for a cash out re-fi (can be a conventional mortgage which would be better terms), and one for buying the investment property (commercial loan department of a bank).If you don't need to finance any construction/rehab, I'd recommend republic bank.
