I have not worked with a portfolio lender myself, but they generally charge a higher interest rate than conventional lenders.

What do you charge for a pet deposit and pet rent in Austin, tx?

So either it would be their responsibility or there would be a flat base rate then I would charge them overages if they exceed that amount.

As it is, I’m charging $949(after early payment discount) for a 2bd/1bath SFR in a small town.

If that's the case then you can't charge a late fee until the 5th day of the month.

It all depend what each LLC is doing.If LLC B owns property in State  and receive rent in state B, it only needs to be registered in state B.If LLC A is just a holding, not doing business in state B, but just owning LLC B, it does not have to be registered in state B.The concept of using a holding LLC is multiple.First as you described, if state B does not give you anonymity, you can get the anonymity of state A by having LLC A listed as sole member of LLC B.Also, and it is probably the most important point, if state B does not have good charging order protection for their LLC, you can get the excellent charging order protection of state A protecting your LLC B for outside liability.Delaware and Wyoming are two very good state to get your holding LLC in.

It may sound nice to pay a 5% management fee but the extra fees can add up to be more than the other company that charges 10% with no add-on fees.

To clarify my thoughts I would recommend you find a Flipper that is local to your current market, work with this person as a mentor for no charge. 

(If so, they will probably charge you extra to bring installers out that far).

The chances are you are better off in the short run charging above market rent and then charging the tenants for utilities even if they waste water, gas, etc.
