We donated to a fund to help the residents and someone was generous enough to be matching donations.  

That way, it 1.) buffers out some of the rise and fall of surges in the market, 2.) makes me seem very fair and not greedy, and 3.) there is never (*yet) an instance where I'm trying to explain to them why rent won't drop, even though the fair market shows that the rent should be lower than it is.Yes, it does leave a little money on the table, but it still allows for constant, logical, and generous rent raises.

It appears the units are below market, however with some cosmetic repairs and perhaps some capex's I feel I could increase the rent by at minimum (based on local comps) 68%.I would offer 85% of list and estimated $20,000 in repairs/upgrades (this is probably a generous estimate - the property appears to be in good shape, basically needs a face lift).With all these figures, including the 50% rule, financing with 20% down @ 3.5%, I come out to a profit of $262 per unit and a cash-on-cash return of 9.53%.So, does this seems reasonable?

While there, I turn my phone off and ask lots of questions.Something I’ve noticed is that successful people tend to be very generous with their experiences.

Simple - just be generous with yourself, and assume they'll trash everything in sight and steal the appliances, cabinets, plumbing and electric. 

Lot's of great information here in this very generous community.  

The guests are very generous with their knowledge and examples of how they run their business.  

The Roth portion of another qualified employer plan like a 401k, 403n, etc can be rolled over into the Roth portion of a Solo 401k.The solo 401k does provide the ability to do an in-plan conversion of tax-deferred funds to Roth status (with the corresponding tax implications), and allows for generous new Roth contributions up to $18K per year.A Solo 401k is exempted from Unrelated Debt Financed income taxation (UDFI) when using mortgages to acquire real property.  

I don't have calculated statistical data to back this claim up, and it could be regional, but it often seems that appraisers are more generous when it comes to appraised market rents than they are when it comes to value.I'll not bore you with the math, but the arithmetic is more generous if you do not intend to live in the property than if you do intend to live in the property (If you aren't going to live there, it is in theory possible to have a calculated DTI of 0.000%... which is in part why commercial financing uses DSCR not DTI). 

Achieving economies of scale may best be attained through volume, but learning how to do it on a small scale will pay generous dividends later; pitching the concept to investors will be much easier when you can show concrete results, and extrapolate from those results instead of being forced to rely solely on projections from a concept.
