6.125% has P&I of $2625/month.5.75% has a P&I of $2521/monthThis is a $104 benefit.Paying $4400 more towards principle will reduce your payment to $2598, a $27/month savings.Math says buying the rate down has a larger net benefit to you up front, but it will take you 42 months to break even.

The larger unit will have higher maintenance/cap ex even with coastal environments being harsh on some items.I suspect your expense estimates are far too low especially if you kept the BP calculator default percentages.  

These are all LTR and while he would love some passive income (don't think he necessarily has to give that up) he'd much rather one of us get a larger tax return for us to continue buying more properties.

Hi @Philip Jones,For the refinance aspect, the main factors will be the FICO Score, cash flow of the property, and as-is value.A Higher FICO will let you get a larger loan size and lower interest rate.Good Cash Flow will ensure that your property will be profitable for you and enable you to get the max loan size that your FICO allows for.The As-is Value will play an important role in making sure that you meet the minimum requirement for a DSCR loan of 100k, but also in making sure that the rehab work that has been done provided significant value add.

While they do eat into rental margins the larger profit came from the sale and the added rental profit was not worth the hassle of being a landlord.

But larger repair items such as appliances and mechanical, plumbing, electrical, roof windows doors etc should still fall under the landlord's responsibility.

However, if you have a more extensive portfolio or plan to become larger in the next year or two, I would look for a double-entry system that allows bank reconciliations.

Quadplexes will fall under residential financing, while larger units will move into the commercial space.

Use some for buy and hold (I personally would prefer apartments rather than buying a few single family homes) and some for lending/trust deed investing.In either category, you must know what you are doing, know how to vet the investment, how to vet the sponsor (if investing in a larger fund of some sort), the laws and regulations on the lending side, how to investigate which areas to invest in buy and hold and notes/trust deeds for that matter.So as you have already said several times, lots to think about . . . 

. $250 per turn would be for larger unit and very good job.
