@Melody RaultA lot of specialized tax firms, including mine, serve clients nationwide, using technology.

Also where there are changes in regulations that may require lenders to change servicing agreements which affect who services your loan.I know that's a pain but as things change -- unfortunately, investors will be impacted by changes in the lending industry - and that includes LOAN SERVICING CHANGES.It’s a total cluster between the banks, their loan servicers and their loan servicer’s sub-servicers.

Would you share 3 specific things I should do during my "training period" (if it includes a book, which one)?

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).

Duplexes have less risk:  Mainly because you have less tenant risk (but we will address that on the next paragraph).

Additionally, the estimate for my tax preparation for this year was approximately $1,000 over the cost I paid last year (including the time I paid for them to correct their errors).

Challenges include depreciation in market value (i.e., mobile homes often lose value over time unless they are situated on owned land) and tenant turnover.However, tax advantages include depreciation deductions, which allow you to offset rental income by writing off the property's value over time, and cost segregation, which accelerates certain deductions.

Rental income is subject to tax, but it is also possible to deduct many costs related to owning and maintaining rental property, including property management fees, repairs, and mortgage interest payments.Additionally, for those investors holding properties in Germany for the long-term, the country's capital gains tax law is attractive.

i work full time too, so i can only do one big project at a time, and can only make about 1 offer every 1-2 months.my stock answer to anyone is to invest where they live - and for expensive metros that includes 1-2 hours out. 

DOM can be minimized by a number of different factors including the quality of marketing, rent price, availability to show.
