Good point on the home expense ratios, I should allocate more for repairs.

Summary question:  How would you allocate by extra money saved from my paycheck by percentage between 1) stock piling cash for a 3rd rental property 2) paying down existing mortgages ( I currently own 2 mortgages that have low interest rates) or 3) investing in traditional retirement accounts including ROTH IRAs, etc.Brief Background:I own 2 properties which both have low interest rates. 

This one has a MUD at the southern border of the property I am trying to see if will allow a water / sewer tap sometime in the future or for redundancy / emergency purposes.In Texas and many other states you can pass along the submetered (or allocated) costs of private utilities to cover the cost of the service - the risk is really about the capital costs (hence diligence), and less about run & maintain if you're doing that properly.My point to all this nonsense is that you're already taking on additional risk by evaluating a smaller park, you might as well keep private utilities on the table if they're in good shape, you can get comfortable with them, and use it as a negotiation point for instant equity / further upside.But I can see from your story @Paul Stout that the existing septic there looked like a big problem, and for a small Park could make the entire economics go sideways.

I do essentially all my own work, typically the only exception is if it absolutely requires a building permit for a skilled trade (not just framing and drywall).With an 1842 multi-family that I bought at a discount due to the work needed...you can only imagine the volume of credit card transactions I have (which I go to painstaking lengths to track every single one, and allocate by percentage to which unit it effects, etc).Looking a bit forward, what if I wanted to have a vehicle (truck, naturally) to ONLY use for the purposes of working on the property/properties?

And do you think there's an appropriate allocation of your assets (between old strategies and new) that would make sense to help increase IRR, but mitigate the risk of doing something new?

The partnership agreement should mention items like allocation of income/losses, expected winedown of partnership, each partner's rights etc.You should then reach out to an agent; it appears that one is recommended to you.You should then communicate with a portfolio lender.

May increase the allocation to 25% if I don’t get any rentals. 

Not surprisingly, we're seeing our highest net worth investors talk of allocating even more capital to our platform while a few smaller investors are sounding more fearful. 

Allocate your time accordingly.I have built my business on the mantra that putting people and principles before profits - profits everyone most.

TIF's can also be called TAD's (tax allocation districts) depending on the area.
