Nothing wrong with this and it will lead to some of the best returns, but you rarely talk about the negatives, chief among them the added risk of more leverage and the necessity to be right about a lot of things. basic finance shows us that if you get over leveraged, you destroy value pretty quick: Again, if the investor has a deep understanding of the market and the time to keep track of the needed variables, this can be quite profitable.

Photos do not show the rotten floor, termite damaged door frames, leaks that destroyed the cabinets and floors, electrical outlets that are not wired.Then you need to have an escrow company that is NOT his represent you or an attorney, depending on the state. 

This is a normal rate/term refi through Fannie/Freddie so Im sure there wont be as much flexibility on the appraisal part.

That's still just a drop in the bucket if the cat destroys the carpet, but it's manageable.

At the same time I feel that i should give ALL focus to real estate so i know as much as possible so when a chance comes in front of my mind/eyes, i won´t miss it because i know what to do/read the situation but at the same time, my mind goes back to "but if you start a affiliate business you will have high cashflow each month  and get faster to your goal.

My agent has a good network and has calls out to his colleagues but nothing in our ROI range that doesn't require significant remodeling or an obscure raise in rent that wont work for the location.

Sure 1) Select and aquire solid properties built by top shelf home builders2) Acquire these properties in good neighborhoods that attract quality tenants that have an incentive to protect their own reputation so they won't destroy yours or your property or engage in conduct detrimental to all.3) Put into place solid property management that understands that their role isn't just to collect rent and fix toilets, but to protect you from liability in all areas that flow from property management like fully vetted tenant selection processes.4) Adequate solid property casualty and liability insurance for each property.5) As/if necessary umbrella insurance coverage tailored to your personal risk profile and risk mitigation goals. 

If you arent doing deals now if you dont have experience your probably wont be doing deals when the lending tightens up or drys up.

Problem is, the lender I am using wants me to use my LLC for the purchase otherwise I wont get funding approved. 

Be humble but firm, and cordial so he does not destroy your property and do not renew the lease.
