I certain percentage of the monthly income should go toward capital expenses so you can save up for things like floods, new roofs, etc.I would be concerned about package deals. 

Makes it easier to save and less capital tied up in the deal.It really depends on the lender and what percentage of your rental income they count for.

Since the maximum loan size is a percentage of current worth (plus rehab money if any), the actual loan size that will be lent to you will generally only be known once an appraisal is done.

@Jay Patel was referring to percentage of rent to your property price.

I've heard they're willing to budge on their initial price a little bit, however it's not likely that they'll accept and offer with a decent percentage price decrease.

In my opinion, without even looking at the report, this would very likely be a bad idea getting stuck paying on $34k of hard money, and the percentage that represents is way too much for a BRRRR deal. 

The higher valuations make it difficult to cover the mortgage and reserves with the lower rents.B is a good area, but not as valued as A.C and D areas will have a higher percentage of people that rent vs. the A areas.

In most instances they charge the first months rent as a finders fee plus a percentage of the take per month.  

She will receive the initial "buy" amount that we agreed on, a portion of which is going to be paid up-front in order to bring her mortgage current and give her enough to move out to Ohio, and then a percentage of the final sale amount.The reason this flip works is because we are avoiding going through two purchases and also avoiding financing fees from a HML on the purchase of the house, since the owner will still own the house during renovations.Since she doesn't own the house outright, this isn't really "seller financing," but maybe more like a joint venture?

All of your reserve percentages are too low.
