Build your ability to spot a good deal quickly, and to estimate repair costs, so that you can make a decision quickly if the right deal pops up.

I buy triplexes and fourplexes because of the cash flow and the ability to get concentional 30 year fixed rate mortgages.

With that said you have to ability to acquire more rental properties and feed the system you have created with your PM.

Buyer must represent "financial ability to perform" (if not contingent on sale of home, etc.).  

That will put up a guard to keep your personal things out of any legalities done on your business and which is the way to go on forming a business,  Another thing you ought to get any financing so you can include in your offers,  That should make the seller more comfortable with you and your ability to close.  

why is the property on the market (need for cash, moved - down-sizing - family)has it been previously listed - how much and for how long - why didn't it sellwill the seller consider - lease with option with possession - seller take back - a delayed settlement - 1031 exchange - joint venture with hybrid auction marketingdays on the marketalways read the remark section of the listingask the agent for some inside information (off the record) about the propertyWhy are you interested in this property?

(FYI: you have your whole plan rely on your mom's ability to make 60 rent payments to her Child and then be able to get a mortgage that she can not right now)There is no reason for you to accelerate the principal payments, if you are renting to her, you will need to keep a reserve for maintenance problems or capital expenditures.Why not get a place and rent it out to someone who is NOT your mom and see how that goes.

Does me living there affect our ability to deduct legitimate rental expenses? 

The house looks remarkable; Marcin I'm curious as to how you came up with that particular design scheme through the house.

I am questioning whether or not I should use my ability to finance up to 10 properties per FNMA guidelines just because I can.
