As far as repairs and Capex go, depending on the property, we allocate 7-10% of rent for each (14-20% total).

"The risk that the lender would be left with the home instead of the stream of payments if the borrower defaulted, for any reason, is one that is allocated to the lender under such a contractand2

It is necessary to allocate the time though.

You're at $350 already, though, and I'm not sure you're allocating enough for capital items (that roof has to be replaced before you sell in ten years, which is about $40 a month by itself.)Applying the 50% rule of thumb, assuming 25% down plus the $2000 out of pocket, 5% for 30 years, I get $311 for P&I.

When people giving you advise from NJ/PA, they are still taken lesser risk financially than you are. 2) 2 adults plus 4 children - consider allocating at least $100 more per month for water.

Every cent you have allocated to the seller must now go to the next of kin in line to receive the proceeds.And I respectfully disagree with @Pavel Sakurets .

In other words, records must be maintained "in a manner so that the assets of the series can be reasonably identified by specific listing, category, type, quantity, or computational or allocational formula or procedure."

So if you see lower or higher for a particular property it could simply be the owners preference for how they allocate internal funds.

Besides that with basically every home built prior to 1980 will have some foundation issues because of the clay soil here in Texas, it's a given to allocate for problems. 

Normally the allocation of income should follow the economic effect of transaction.
