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.

How to deal with unexpected situations ... etc. 2% versus 3% versus 4% is not going to make you wealthy at this stage.

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).
